What guns do police use? Today, most law enforcement officers carry full-size or compact semi-automatic pistols chambered in 9mm. Leading models include the Glock 17, Glock 19, Sig Sauer P320, and Smith & Wesson M&P series, selected for their reliability, capacity, and compatibility with duty lights and optics. "Standard issue police pistol" doesn't mean one single gun nationwide; it means whichever pistol your specific department, or in some cases you personally, has chosen from an approved list.
Police handgun choices have evolved from double-action revolvers to striker-fired platforms that support modern tactical needs. Whether it's uniformed patrol, detective work, SWAT, or off-duty carry, each role calls for a different balance of concealability, capacity, and control.
This guide breaks down the most common handguns in law enforcement, why they're chosen, how they differ by agency and assignment, and what specific major departments like the FBI, NYPD, and LAPD actually carry right now.
| Model | Caliber | Use Case | Agency Examples | Notable Features |
|---|---|---|---|---|
| Glock 19 | 9mm | Primary duty & off-duty | FBI (Glock 19M), NYPD, many municipal PDs | Compact size, high reliability, optics-ready options |
| Glock 17 | 9mm | Full-size duty | FBI, NYPD | Full-size grip, higher magazine capacity than the 19 |
| Glock 22 | .40 S&W | Uniformed patrol | State Police, Highway Patrol | Higher capacity, .40 stopping power |
| Sig Sauer P320 | 9mm | Standard duty | U.S. Military, DHS | Modular chassis, M17/M18 military variant |
| Smith & Wesson M&P9 | 9mm | General duty & tactical | ICE, Local PDs | Ergonomic design, ambidextrous controls |
| FN 509 | 9mm | Duty & SWAT use | LAPD (FN 509 MRD-LE) | Military trial-tested, high durability |
What Handguns Do the FBI, NYPD, and LAPD Actually Issue?
Generic "police pistol" answers only go so far, since standard issue genuinely varies by agency. Here's what three of the country's most-searched departments currently carry.
FBI
The FBI's standard-issue sidearm is the Glock 19M, a compact 9mm built to the Bureau's own specifications, alongside the full-size Glock 17 for agents who prefer a larger grip.
The Bureau adopted the 19M in 2016 through an $85 million contract, replacing the .40 S&W Glock 22 and Glock 23 that agents had carried since the late 1990s.
The switch back to 9mm followed advances in defensive ammunition that closed the performance gap with .40 S&W while offering less recoil, faster follow-up shots, and higher magazine capacity, advantages that matter for an agency where every agent must qualify regardless of hand size or experience level.
NYPD
New NYPD officers currently choose between the Glock 17 Gen 4 and Glock 19 Gen 4 as their primary duty sidearm.
Legacy officers may still carry the Smith & Wesson 5946 or Sig Sauer P226 DAO, both no longer issued to new recruits. NYPD-issued Glocks historically ran a heavier 12-pound NY-2 trigger pull, a modification intended to reduce negligent discharges, though the department moved new recruits to a standard 5-pound trigger starting in 2021 after data showed it improved accuracy.
Approved off-duty and plainclothes options include the Glock 26, Sig Sauer P365, and Springfield XD-S.
LAPD
The LAPD's standard duty pistol is the FN 509 MRD-LE, adopted in January 2022. Before that, the department issued the Glock 22 in .40 S&W, and before 2002, the Beretta 92F was standard. LAPD SWAT carries a separate platform, a Kimber Custom TLE II 1911 in .45 ACP, reflecting the specialized role that unit fills compared to uniformed patrol.
Do Detectives Carry Guns?
Yes, detectives carry firearms, typically the same duty-caliber pistol as patrol officers but in a smaller, easier-to-conceal frame suited to plainclothes work.
Where a uniformed patrol officer might carry a full-size Glock 17 openly on a duty belt, a detective more commonly carries a compact model like the Glock 19 or 26 in an inside-the-waistband or support-side pocket holster, since concealment, not open deterrence, is the priority for investigative work.
Historically, this same logic drove detectives toward snub-nose revolvers like the S&W Model 10 Snub, back when uniformed officers carried longer-barreled duty revolvers. The gear has changed; the underlying reason, a smaller gun for plainclothes concealment, hasn't.
Glock 17

The Glock 17 is a full-size, striker-fired, polymer-framed handgun chambered in 9mm. It features a 17+1 round standard capacity and is engineered for durability under high-round-count duty use.
The firearm's Safe Action System includes three passive safeties, trigger, firing pin, and drop safety, which reset automatically after every shot.
This passive-safety design is also the direct answer to a common question: standard police pistols like the Glock 17 don't have a manual thumb safety the way a 1911 does; they rely instead on these internal passive mechanisms plus trigger discipline.
Key design elements include a 4.49-inch cold-hammer-forged barrel, polygonal rifling, and a low bore axis for reduced muzzle flip. The slide is typically finished with Glock's nDLC or Tenifer process, increasing corrosion resistance and surface hardness.
The Glock 17's wide parts interchangeability and low-maintenance requirements have made it a standard-issue sidearm for numerous law enforcement agencies worldwide, including both the FBI and NYPD.
It is optics-ready in MOS configurations and supports most duty-rated weapon lights.
Glock 19

The Glock 19 is a compact version of the Glock 17, also chambered in 9mm, and features a 4.02-inch barrel with a 15+1 round capacity. Its reduced size makes it suitable for both uniformed duty and concealed off-duty use, offering a balance between shootability and concealability that's a large part of why it's the single most common individual model referenced when people ask what standard issue police pistol looks like today.
The Glock 19 retains the same internal mechanism and Safe Action System as the Glock 17, ensuring familiarity for officers cross-training between platforms.
The MOS variant supports direct mounting of RDS optics, and newer Gen 5 versions include an ambidextrous slide stop lever and a flared magwell for improved reload ergonomics.
Law enforcement agencies favor the Glock 19 due to its compatibility with Glock 17 magazines and holsters, making it logistically efficient while still maintaining full-service capability.
It carries 15 rounds standard, a number worth stating directly given how often people ask specifically how many rounds a standard police pistol holds; a full-size Glock 17 holds 17, and many departments' duty magazines run one round higher still with an extended baseplate.
Glock 17 vs. Glock 19: Which One Do More Departments Actually Issue?
Both are the same basic platform in two different sizes, and the choice between them usually comes down to role rather than performance.
The Glock 17's longer grip and 17-round capacity make it the more common choice for uniformed patrol, where the sidearm is worn openly and concealment isn't a factor.
The Glock 19's shorter grip and barrel trade two rounds of capacity for a size that works equally well on a duty belt or under plainclothes, which is why agencies that want to issue a single pistol for both uniformed and off-duty use, the FBI and NYPD among them, frequently default to the 19 instead of forcing officers to qualify on two different frame sizes.
Neither Glock 19 or Glock 17 has a meaningful edge in reliability or accuracy over the other; both run the same trigger, the same internal mechanism, and accept each other's magazines. The real-world decision is almost entirely about concealment needs versus grip capacity, not raw capability.
Glock 22, Glock 23, and the .40 S&W Holdouts
The Glock 22 (full-size) and Glock 23 (compact) are the .40 S&W counterparts to the 17 and 19, sharing the same frame sizes and control layout but chambered for a cartridge that was, for a long stretch in the 1990s and 2000s, the dominant police caliber nationwide, largely following the FBI's own adoption of .40 S&W after the 1986 Miami shootout exposed shortcomings in the ammunition agents carried at the time.
Some state police and highway patrol agencies still issue the Glock 22 today, valuing its slightly higher power over 9mm, but the broader trend across nearly every level of law enforcement has been back toward 9mm, following the same ammunition-performance logic that led the FBI itself to switch back in 2016.
Glock 22 vs. Glock 19: Key Differences and Why Officers Prefer the Glock 22
The Glock 22 and Glock 19 might seem similar at a glance, but they diverge in crucial ways that shape their usage among law enforcement officers.
Size and Weight Differences
While both firearms share a recognizable design, the Glock 22 is distinctively longer and heavier. This enhanced size provides certain advantages in terms of balance and handling, particularly in high-pressure scenarios.
Ammunition Versatility
One of the standout features of the Glock 22 is its ability to chamber both 9mm and .40 caliber rounds. This flexibility offers a powerful alternative to the Glock 19, which is primarily designed for 9mm ammunition.
The transition from a 9mm to a .40 caliber gives officers increased stopping power without sacrificing control—crucial in tactical situations.
Concealability Factor
The Glock 19 remains a favorite for officers whose roles prioritize discretion and concealment. However, when concealment is not a priority, the Glock 22 gains preference due to its additional firepower.
Bridging the Caliber Gap
Historically, there was a gap in firearms: between the heavier .45 caliber and the more compact 9mm options. The Glock 22 fills this void, combining the power associated with larger calibers and the maneuverability of smaller models. This combination makes it a trustworthy choice for law enforcement professionals globally.
In summary, the Glock 22 stands out with its enhanced power, adaptability to different ammunition types, and effective balance of size and capability, making it a preferred choice for many officers in the field.
Glock 34 and Glock 19X: The Less Common Duty Variants
Two other Glock models get named regularly in police contexts without much explanation of what sets them apart.
The Glock 34 is a long-slide, competition-oriented variant built on the Glock 17 frame with a longer 5.31-inch barrel and slide. The extended sight radius improves practical accuracy at distance, which is why some departments authorize it for officers who compete in duty-pistol competitions or simply prefer the flatter shooting characteristics a longer slide provides, even though its added length makes it a less common choice for daily concealed or plainclothes carry.
The Glock 19X is a hybrid: it pairs the longer, full-size Glock 17 slide with the shorter Glock 19 frame, a configuration originally developed for the U.S. Army's Modular Handgun System trials before Sig Sauer's P320 won that contract.
Glock released the 19X commercially afterward, and it has since picked up some law enforcement adoption among officers and agencies who want the sight radius and slightly softer recoil impulse of a full-size slide on a more concealable compact frame.
Sig Sauer P320

The Sig Sauer P320 is a modular, striker-fired pistol platform designed around a serialized fire control unit (FCU), which allows the core mechanism to be transferred between full-size, compact, and subcompact grip modules.
Chambered primarily in 9mm for law enforcement applications, the P320 features a 4.7-inch barrel (full-size) and a 17+1 capacity in its standard configuration.
The P320 platform supports factory and aftermarket optic-ready slides, X-Series performance upgrades, and flat-faced triggers for enhanced control. Its polymer grip modules vary in size and texture to match department preferences or officer hand sizes.
Law enforcement agencies select the P320 for its modularity, drop safety certification, and increasing cross-compatibility with military configurations, including the M17 and M18 variants used by the U.S. military.
Smith & Wesson M&P Series

The Smith & Wesson M&P9 and M&P40 are striker-fired duty pistols developed specifically for law enforcement and military markets.
The full-size M&P9 features a 4.25-inch barrel, 17+1 round capacity, and a steel-reinforced polymer frame with interchangeable backstraps for ergonomic adjustment.
The pistol's hinged trigger safety, low bore axis, and tactile reset allow for efficient training transfer across skill levels.
The M2.0 variant added an enhanced grip texture, crisper trigger break, and forward slide serrations.
Duty configurations include thumb safety versions, optics-cut slides, and integrated Picatinny rails for light and laser compatibility. M&P pistols are widely adopted by U.S. federal, state, and municipal law enforcement agencies due to their durability, adaptability, and intuitive controls.
FN 509

The FN 509 is a striker-fired, polymer-frame handgun developed from FN America's submission to the U.S. Army's Modular Handgun System trials. Chambered in 9mm, it features a 4-inch cold hammer-forged barrel, 17+1 capacity, and fully ambidextrous controls, including slide stop and magazine release.
The FN 509 Tactical variant includes an optic-ready slide, suppressor-height night sights, and a threaded barrel, supporting advanced patrol or tactical configurations. The pistol's aggressive slide serrations and high-grip texturing improve handling under stress or adverse conditions.
LAPD's adoption of the FN 509 MRD-LE as its standard duty pistol highlights the platform's real-world viability for law enforcement patrol and tactical deployment. Its drop safety performance, accuracy standards, and modular upgrades make it a strong choice for departments seeking a rugged, optics-compatible sidearm.
9mm vs. .45 ACP: Why Police Chose One Over the Other
Choice of caliber has swung back and forth over police history, and 9mm's current dominance is a relatively recent development driven by ammunition, not just preference.
.45 ACP offers a larger, heavier bullet, and for decades it was seen as the harder-hitting choice, which is part of why it saw real use in specialized units like LAPD SWAT's 1911s.
But .45 ACP's larger cartridge means lower magazine capacity in a similarly sized grip, more felt recoil, and slower follow-up shots, all real costs for an officer who needs to shoot accurately and quickly under stress.
Modern 9mm defensive ammunition closed the performance gap that once favored .45 ACP, delivering expansion and penetration that's now considered functionally comparable in most defensive scenarios, while still offering higher capacity, less recoil, and faster training for a wider range of officers regardless of hand size or experience.
That combination is exactly why agencies like the FBI moved back to 9mm in 2016 after years of issuing .40 S&W, and why almost no department insists on .45 ACP as standard issue today.
.45 ACP still sees use, mostly in specialized units running 1911-pattern pistols rather than as a mainstream duty caliber.
Auxiliary and Backup Handguns in Law Enforcement
Yes, many police officers do carry a second handgun, especially those in patrol, undercover, or tactical roles.
These backup weapons serve as a contingency tool: if the primary duty weapon is inaccessible, damaged, or forcibly taken, the secondary firearm provides a last line of defense.
Why Officers Carry a Backup Gun
Backup guns are selected for concealability, ease of access in compromised positions, and compatibility with duty ammunition (typically 9mm). Departments often allow them under policy conditions such as:
- Firearm must be from an approved list or meet minimum safety criteria
- The officer must qualify with the backup weapon
- The gun must be carried in a department-approved holster (ankle, vest, or pocket-mounted)
Common Backup Handgun Locations
- Ankle holsters (for seated access or patrol backup)
- Vest holsters (commonly placed on the external carrier)
- Support-side pocket (especially for detectives or plainclothes units, the same concealment logic covered above)
What Are the Most Common Backup and Off-Duty Handguns Used by Police?
These compact and subcompact models dominate in law enforcement backup and off-duty carry:
- Glock 43 / 43X: Single-stack 9mm with 6 to 10-round capacity. Ultra-thin profile ideal for ankle or vest carry. Matches manual of arms with Glock duty pistols.
- Sig Sauer P365: One of the most popular subcompacts due to its 10 to 15-round magazine capacity in a tiny frame. Offers night sights and RDS-compatible versions, and is one of NYPD's currently approved off-duty options.
- Smith & Wesson M&P Shield Plus: Offers 10+1 or 13+1 capacity in 9mm. Slim and consistent with full-size M&P ergonomics.
- Glock 26: A slightly thicker subcompact that still offers 10-round capacity and accepts Glock 17/19 magazines. A common choice for officers who want Glock familiarity in a smaller frame, and another NYPD-approved off-duty option.
Off-duty carry and on-duty backup carry solve overlapping but distinct problems.
A backup gun rides alongside the duty pistol during a shift as insurance against losing access to the primary.
An off-duty gun is what an officer carries entirely on their own time, chosen for daily concealability the way any civilian concealed carrier would choose a gun, just from a department-approved list rather than an open market.
The same handful of compact 9mm pistols above tend to serve both roles well, which is why they show up on nearly every department's approved list for both purposes.
When Is a Backup Gun Used?
Real-world use of backup guns typically occurs during weapon retention struggles, when seated or downed and the duty weapon can't be reached, or in low-visibility conditions where primary access is compromised.
Departments with high-risk operational profiles, large urban police departments or SWAT divisions, are more likely to formalize secondary carry in their policies.
The Revolver Era: Police Sidearms from 1900 to 1980s
Throughout most of the 20th century, double-action revolvers were the standard sidearm for police departments across the United States.
Agencies favored them for their simplicity, reliability, and ease of training. The majority were medium-frame revolvers chambered in .38 Special, with six-round cylinders, fixed sights, and steel frames.
Core Duty Models: Smith & Wesson and Colt Dominance
Two manufacturers dominated police service revolvers during this era: Smith & Wesson and Colt.
- Smith & Wesson Model 10 (originally the .38 Hand Ejector, 1899): This became the gold standard for police sidearms. By the mid-20th century, it was the most issued duty revolver in the U.S., with 4-inch barrels being most common for uniformed officers and 2-inch "snub-nose" versions for detectives and plainclothes units.
- Colt Police Positive (introduced in 1907): Known for its innovative "Positive Lock" internal safety system, it helped prevent accidental discharges if the weapon was dropped. It was issued widely and chambered primarily in .38 Special and .32 Colt.
- Colt Official Police: Similar to the Police Positive but beefed up for .38 Special loads. It saw widespread use in large departments during the mid-20th century.
Concealed Carry and Plainclothes Configurations
Detectives and off-duty officers typically carried shorter-barreled revolvers, often with round butt frames for better concealment.
Models like the S&W Model 10 Snub, Colt Detective Special, and eventually the S&W Model 13 (FBI standard from 1981 to 1991) filled this role.
The Rise of Magnum Revolvers (1950s-1970s)
While the .357 Magnum was introduced in the 1930s, high cost and recoil limited its adoption until the post-WWII era.
By the 1950s and 60s, concerns over increased firepower among criminals led to growing interest in magnum-capable revolvers.
- S&W Model 19: A K-frame .357 Magnum that balanced power and portability. Popular for highway patrol officers.
- S&W Model 586 (L-frame): Created in the 1980s to solve durability issues with the Model 19. Designed to withstand regular use of full-power .357 loads.
- Colt Python: Arguably the most refined magnum revolver of the period. Expensive, hand-fitted, and considered a premium option, carried by those who could afford personal purchase.
- Ruger Security Six & Speed Six: Introduced in the 1970s, these rugged revolvers were affordable, strong, and became common in some departments before the switch to semi-autos.
Why the Revolver Era Ended
By the late 1980s and into the 1990s, revolvers were being phased out for three main reasons: limited six-round capacity that no longer matched higher-capacity semi-autos, reload speed that couldn't compete with magazine-fed pistols even with speedloaders, and a training burden from DA/SA triggers and heavier recoil compared to modern striker-fired pistols.
Do Police Still Use Revolvers Today?
No major U.S. municipal or state police department currently issues a revolver as its standard duty sidearm.
The last large agencies to retire theirs did so decades ago; NYPD, for instance, phased out its remaining revolvers by 2017.
Revolvers do still turn up in isolated, specific contexts: some smaller rural departments with limited budgets, a small number of grandfathered personal off-duty guns predating a department's switch to semi-autos, and continued use in some countries outside the U.S.
But as a matter of standard issue for an active-duty American police officer today, the revolver era is over, and has been for more than a generation.
Early Semi-Auto Police Pistols
Early police semi-auto use was mostly in urban departments. It was socially unwelcome for even police to open carry their duty weapons, so most police officers of the 19th century and much of the 20th century would conceal their duty guns in pocket or under a jacket.
Early police semi-autos were compact medium-bore pistols like the Colt 1903 Pocket Hammerless (favored by the Boston Police Department and Shanghai Municipal Police, largely made up of British expats) and later the Walther PP series, which was created for the German police.
Some departments would adopt or authorize civilian M1911 pistols, especially the .38 Super variants in the 1930s.
While never popular for mainstream police use, the 1911 pistol would catch on in select police units (such as LAPD SWAT, LAPD SIS, the FBI's Hostage Rescue Team, and select FBI SWAT units) in the 1970s and 80s.
The Commander model would also find some popularity in plainclothes use as well.
One of the first semi-autos after the 1911 to see much police use was the Smith & Wesson autos.
Early adopters included the Illinois State Patrol, who issued the Model 39 (a single-stack 9mm DA/SA pistol), and the Bakersfield Police Department, who adopted the Model 59 (same upper and barrel, double-stack magazine) when it came onto the civilian market in 1971.
The second- and third-generation S&W autos like the 459, 5906, 1046, 456, and 4506 were also common police issue from the 1980s into the 2000s.
The other brands to dominate the police market starting in the 1980s and into the 1990s were Glock, Sig Sauer, and Beretta.
The Glock 17, 22, 23, and 19 first gained acceptance in the US police market beginning in the early 1990s, which has grown to the point that Glock is now the single most-common police duty pistol.
Starting with the FBI's adoption of the .40 S&W cartridge, much of the United States' domestic police force switched to this caliber.
Almost all of the common police issue pistols of the day were chambered for it, and until fairly recently most pistols based on a 9mm frame-size would likewise be offered in that caliber.
Sig Sauer's P220, P226, and P229 DA/SA pistols were common police issue for state and local departments as well as federal agencies like the FBI, Border Patrol, and beyond, in fact remaining common into the early 2000s.
The Beretta M9/92FS pistol, another one of the high-capacity "Wonder Nines," was also a common police duty pistol (as well as the 96FS, chambered in .40 S&W) for the last quarter of the 20th century, as many officers had gained familiarity in military service.
H&K managed to make some inroads into the law enforcement market with the USP series.
Modern police duty pistols, however, are quite different.
Modern Police Handguns
The modern police handgun is a full-size or compact polymer-framed striker-fired pistol, usually chambered in 9mm but with a few holdouts still clinging to .40 S&W. Almost no departments insist on .45 ACP anymore.
The typical police pistol of today has, at minimum, night sights, if not a milled slide for accepting a red dot sight. The frame is railed for mounting a pistol light, usually a full-size light such as the Streamlight TLR-1, SureFire X300, or Modlite PL350.
The Glock 17 and 19, as well as iterations such as the 19X, 45, and 34, and now the Border Patrol's duty pistol, the Glock 47, are the most common, with the .40 caliber Glocks (22, 23) also still represented in the field.
Smith and Wesson's newer generation of duty pistols, the M&P series, is somewhat common, with the M&P9 and M&P40 (both original and M2.0 versions) far from uncommon in police use in the United States.
Sig Sauer's P320 pistol made a splash as the new issue handgun of the US military (in M17/M18 guise) and has found some adoption in US (and foreign) departments as well.
The LAPD went in a different direction altogether, adopting a variant of the FN 509 for standard issue in 2022.
Common auxiliary pistols include all of the above, but many departments will allow officers to supply their own gun. The Sig Sauer P220 series is commonly approved for duty use, as well as Berettas, and in more recent years, Staccato 2011 pistols as well.
The modern duty gun is vastly different than what police officers had to use even as recently as 30 years ago.
Why Law Enforcement Officers Favor the Glock 19
The Glock 19 remains a top choice among law enforcement officers, thanks to its array of practical features and characteristics that meet their demanding needs.
- Durability and Reliability: Officers need firearms that can withstand heavy use in various environments. This model is renowned for its robust construction, ensuring it performs reliably even in extreme weather conditions.
- Ease of Maintenance: Its straightforward design simplifies cleaning and maintenance, so officers can focus on their duties rather than complex disassembly and reassembly.
- Versatility: The Glock 19 is designed to handle different shooting scenarios, making it suitable for both on-duty use and undercover assignments.
- Accuracy and Stopping Power: Officers have praised the weapon for its precision and effective stopping power in high-pressure situations.
These features collectively make this firearm a preferred choice for law enforcement professionals around the globe.
Best Off-Duty Carry Options for Law Enforcement Officers
Off-duty carry priorities differ from patrol duty: an officer off the clock wants a smaller, easily concealed pistol rather than a full-size duty gun worn openly on a belt. Several compact 9mm options dominate this category today.
The Sig Sauer P365 has become one of the most widely carried off-duty guns in law enforcement, packing a 10 to 15-round magazine into a genuinely pocket-sized frame, and it's on NYPD's own approved off-duty list.
The Glock 43X and Glock 26 both offer the advantage of a manual of arms identical to the duty-size Glock 17 or 19 many of these same officers carry on shift, meaning no retraining is needed to switch between the two.
The Smith & Wesson Shield Plus rounds out the category with a slim, reliable frame and a trigger similar to full-size M&P duty pistols.
All four share the same underlying logic: enough capacity and stopping power to matter in an actual defensive encounter, small enough to disappear under regular clothing, and, in most cases, close enough in operation to an officer's duty pistol that switching between the two doesn't require separate training.
Duty Pistols Reflect the Realities of Law Enforcement
The handguns carried by police officers aren't chosen at random. They're the result of decades of evolution in firearms engineering, agency policy, and tactical necessity.
Whether it's the widespread use of the Glock 19, the modularity of the Sig Sauer P320, or the specialized adoption of optics-ready platforms like the FN 509, each model reflects how departments balance performance, reliability, and logistics.
Modern duty pistols must support attachments like weapon lights and red dot sights, meet drop safety standards, and perform in a range of urban and rural scenarios. But choosing the right sidearm is only half the system.
These handguns demand equally capable duty holsters, retention-rated, optic-compatible, and built for consistent access under stress.
Understanding what handguns police use provides more than trivia. It highlights how critical gear selection is for those who carry not by choice, but by profession.
Frequently Asked Questions
What are the most common handguns issued to police officers in the United States?
Police officers most frequently carry full-size or compact 9mm striker-fired pistols. Leading models include the Glock 17, Glock 19, Sig Sauer P320, Smith & Wesson M&P9 M2.0, and the FN 509 MRD-LE, chosen for reliability, high-capacity magazines, ease of maintenance, and widespread agency support.
Do all police departments use the same handgun models?
Handgun selection varies by agency based on department policy, regional preferences, and procurement contracts. NYPD officers choose between the Glock 17 Gen 4 and Glock 19 Gen 4, the FBI issues the Glock 19M and Glock 17, and the LAPD carries the FN 509 MRD-LE. Departments such as Chicago PD approve a range of striker-fired 9mm pistols across several brands rather than mandating one model.
Do detectives carry guns?
Detectives carry firearms just as patrol officers do, typically a compact duty-caliber pistol like the Glock 19 or 26 carried in an inside-the-waistband or pocket holster for plainclothes concealment, rather than the full-size duty pistol a uniformed officer wears openly.
Do police still use revolvers?
No major U.S. police department currently issues a revolver as its standard duty sidearm; the last large agencies retired theirs decades ago, and modern semi-automatic pistols replaced revolvers for capacity, reload speed, and training reasons starting in the late 1980s. Isolated exceptions exist in some smaller departments and grandfathered personal off-duty guns, but revolvers haven't been mainstream standard issue for well over a generation.
How many rounds does a standard police pistol hold?
A standard full-size police pistol like the Glock 17 holds 17 rounds in its factory magazine, while the more common compact Glock 19 holds 15, and many departments issue an extended baseplate that adds one or two rounds beyond factory capacity. Total capacity carried on duty is usually higher still, since most officers carry at least one reload on their duty belt in addition to the loaded pistol.
Do police guns have safeties?
Standard police pistols like the Glock, Sig P320, and M&P series rely on passive internal safeties, a trigger safety, firing pin safety, and drop safety, rather than a manual thumb safety an officer has to switch off before firing. This design is intentional: it removes an extra step that could slow a defensive draw under stress, with the trigger itself serving as the primary safety mechanism.
Why are Glock pistols so widely used by law enforcement?
Glock pistols, including the 17, 19, 22, and 45, are valued for their proven reliability, simple operation, and consistent performance under adverse conditions. Their polymer frames, high round capacity, and user-friendly maintenance contribute to their broad adoption across thousands of departments nationwide.
How does the Sig Sauer P320 compare for police duty use?
The Sig Sauer P320 is recognized for its modular fire control unit, ambidextrous controls, and agency-friendly features like customizable grips and optional manual safeties. It has been widely adopted by federal agencies and some large city police departments, complementing or replacing Glocks as their standard-issue pistols.
Are there any newer models gaining popularity among police?
The FN 509 MRD-LE, adopted by the LAPD, is rapidly gaining traction due to its milled slide for red dot optics, robust build quality, and success in rigorous law enforcement testing. Its 17-round capacity and enhanced ergonomics make it a strong contender for modern police duty pistols.
Do specialized police units carry different handguns?
Special units such as SWAT or detective bureaus may issue or allow 1911-style pistols (like the Staccato P 2011), HK VP9, or compact submodels like the Glock 26 or Sig Sauer P365 for off-duty and backup carry. LAPD SWAT specifically carries a Kimber Custom TLE II 1911 in .45 ACP, separate from the department's standard-issue FN 509. These choices prioritize high accuracy, ease of concealment, and personal fit for specialized roles.
What guns do state troopers and sheriffs carry?
State troopers and sheriff's deputies generally carry the same category of full-size or compact 9mm striker-fired duty pistols as municipal police, with the specific model depending entirely on the individual state agency or county's procurement contract. The Glock 22 in .40 S&W remains more common among state police and highway patrol agencies than among municipal departments, reflecting some state agencies' slower transition away from .40 S&W compared to city police forces.
What features are agencies looking for in duty pistols?
Key requirements include high reliability, inherent safety mechanisms, accessory rails for weapon lights, night sights or optics-ready slides, manageable recoil, and grips that fit a wide range of hand sizes. Agencies increasingly seek models with modular backstraps and enhanced trigger systems.
Do police officers provide their own handguns?
Some agencies allow approved personal firearms to be carried on duty, provided they meet departmental specifications. Most, however, issue standardized pistols to streamline training, maintenance, and supply needs.
Are police handguns different from those available to civilians?
Most police duty pistols are also available to civilian buyers with nearly identical features, aside from markings or optional law enforcement-only upgrades. This includes Glock, Sig Sauer, Smith & Wesson, and FN models widely found in the civilian market. Agency-specific variants like the FBI's Glock 19M do see limited civilian production runs, though the standard Gen 5 equivalent is far easier for a civilian buyer to find.
