The Colt Mustang XSP is a polymer-framed, single-action subcompact pistol chambered in .380 ACP, introduced in 2013 as a modern evolution of Colt’s classic Mustang line. It features a 2.75-inch barrel, 6+1 capacity, and weighs just 11.8 ounces unloaded.
Designed for deep concealment, the XSP merges 1911-style controls with a modern polymer frame, updated ergonomics, and a small accessory rail under the trigger guard. While praised for its light weight, crisp trigger, and compact profile, it has drawn criticism for inconsistent reliability, particularly with defensive hollowpoint ammunition.
Colt’s history with compact .380 ACP pistols stretches back to the 1980s, when the original Colt Mustang debuted as one of the first truly shootable pocket autos. By 2013, Colt decided to bring that design into the 21st century with the Mustang XSP—a lightweight, polymer-framed variant that maintains the spirit of the 1911 in a deep-concealment format.
The Mustang XSP arrived at a time when pocket pistols were evolving. Competitors like the SIG Sauer P238 (itself a Mustang derivative), Ruger LCP, and S&W Bodyguard 380 dominated the market. Colt’s goal was to blend its legacy craftsmanship with modern materials and ergonomics, creating a premium alternative for concealed carry.
With its single-action trigger, ambidextrous safety, and slim frame, the XSP offers a familiar manual of arms to anyone accustomed to 1911 pistols—but in a form factor small enough to disappear in a pocket holster.
Colt Mustang XSP Specifications
Colt Mustang XSP Design & Build Quality
Colt’s decision to move to a polymer frame set the XSP apart from every previous Mustang. The result is a pistol that feels feather-light yet well-balanced in the hand.
Frame and Slide
The polymer frame features molded grip texturing that offers improved traction over the slick aluminum Pocketlite. The undercut trigger guard and angled beavertail allow a higher grip for better control. The stainless-steel slide, treated with a Diamond-Like Carbon (DLC) finish, provides corrosion resistance and a premium matte sheen.
Ergonomics
The Mustang XSP’s ergonomics are a significant leap forward. The 1911-style thumb safety, slide stop, and mag release are intuitively placed, although their small size requires deliberate manipulation.
Shooters accustomed to full-size 1911s will feel immediately at home—though the downsized controls take adjustment.
The grip texture and trigger reach accommodate a wide range of hand sizes, offering solid retention despite its small footprint. Colt’s addition of an accessory rail—rare for pistols in this size class—adds versatility for a light or laser.
Fit and Finish
While lightweight, the XSP feels solid, with tight slide-to-frame fit and crisp machining. However, user reports note that the polymer frame may show wear at the slide rails after heavy use, though this rarely impacts function.
Colt Mustang XSP Variants & Model Differences
The Mustang XSP represents the modern iteration of Colt’s small-frame .380 lineup.
Mustang Pocketlite
-
Aluminum frame, no rail, and smoother contours.
-
Slightly heavier (~13.7 oz) but often considered more durable.
-
Favored by those seeking the “classic” Mustang feel.
Mustang XSP
-
Polymer frame reduces weight by nearly two ounces.
-
Adds accessory rail, improved grip texture, and better trigger guard undercut.
-
Blacked-out tactical aesthetic versus the Pocketlite’s silver finish.
Comparable Pistols
-
SIG P238: Mechanically identical lineage but all-metal and more refined. Typically offers better reliability at higher cost.
-
Ruger LCP II: DAO trigger, lighter, but less shootable and smaller sights.
-
S&W Bodyguard 380: Integrated laser option, heavier trigger, lower price point.
The XSP sits between these—premium in feel and design, yet inconsistent in performance.
User note: “The Colt Mustang XSP fills an appealing niche as a lightweight, 1911-style, polymer-frame .380 carry pistol with enhanced ergonomics and sights. Owners praise its handling and concealability but often experience (and warn about) inconsistent reliability with defensive ammo and certain magazines. At its price point, the XSP is attractive for some but surpassed by competitors (notably the SIG P238) in real-world reliability and out-of-box confidence.”
Performance
Accuracy
At defensive distances (7–10 yards), the XSP performs admirably. Its fixed barrel and single-action trigger make it capable of one-hole groups at 7 yards and 2–3” spreads at 15 yards. Beyond 20 yards, sight radius and grip length limit precision.
Trigger
The trigger is the XSP’s standout feature. Breaking cleanly at around 5 pounds, with a short, tactile reset, it’s markedly superior to most DAO pocket pistols. It allows faster follow-up shots and more precise trigger control than competitors like the LCP or Bodyguard 380.
Recoil Management
Despite its low weight, recoil is relatively mild. The locked-breech design absorbs much of the .380’s impulse, making it comfortable to shoot even for extended sessions. Grip design helps maintain control, though large-handed shooters may find it cramped.
Reliability
Here lies the XSP’s most divisive aspect. Reports of failures to feed (FTF) and stovepipes are not uncommon, particularly with hollowpoints or flat-nose ammunition. The pistol tends to favor 95-grain FMJ or ball ammo, which cycles smoothly.
Some users report flawless reliability after break-in (200+ rounds), while others experience persistent issues—even after magazine or ammo changes.
Colt’s customer service generally resolves major defects, but it’s a recurring theme among owners.
Ammunition Compatibility
The Mustang XSP is chambered for .380 ACP, and while it’s +P capable, consistent use of overpressure rounds isn’t advised due to frame wear.
Recommended Loads
-
Range Practice: Winchester White Box 95-grain FMJ, Blazer Brass 95-grain FMJ
-
Defensive: Hornady Critical Defense 90-grain FTX, Federal Hydra-Shok 90-grain JHP, Speer Gold Dot 90-grain JHP
The XSP runs best with rounded-nose ammunition, as some hollowpoints hang up on the feed ramp. Regular cleaning and lubrication improve feeding consistency.
Use Case Suitability
Concealed Carry
The Mustang XSP excels in concealability. Its lightweight polymer frame and small footprint make it ideal for pocket, ankle, or appendix carry. However, users should thoroughly test reliability with their chosen defensive load before trusting it for daily carry.
Home Defense
While the XSP can serve in a pinch, its limited capacity and small frame make it less ideal than larger-caliber handguns. Still, its intuitive controls and mild recoil make it approachable for shooters with limited experience.
Competition or Training
Not suited for formal competition due to its size and caliber, but an excellent training platform for new shooters transitioning to 1911-style triggers.
Recreational Range Use
At the range, the XSP is genuinely fun to shoot. The single-action trigger and low recoil make it enjoyable for casual sessions or new shooters learning fundamentals.

Final Verdict
The Colt Mustang XSP is a thoughtful modernization of an American classic. It retains the timeless appeal of the 1911 in a polymer subcompact form—complete with manual safety, clean trigger, and Colt heritage. As a deep-concealment pistol, it’s exceptionally easy to carry and surprisingly accurate for its size.
However, its inconsistent reliability remains a sticking point. Shooters who experience trouble-free function often love it; those who don’t, trade it quickly. At its price, it faces stiff competition from the SIG P238, which offers comparable ergonomics with a stronger track record.
For those willing to invest time testing ammo and magazines, the Mustang XSP rewards with a capable, enjoyable, and classic-feeling pocket pistol that bridges tradition and innovation.
