Considerations
If you prefer a straightforward pistol with proven field performance and extensive aftermarket support, choose the Glock 17. For those prioritizing versatility in configuration alongside modern enhancements suited for dynamic roles, opt for the Glock 47.
Key Specs Breakdown
Design & Ergonomics
The Glock 17 features a full-size frame, offering excellent control for duty use and competitive shooting. Its larger grip accommodates shooters with medium to large hands, ensuring stability during rapid fire. The textured surface enhances your grip under various conditions, including wet or gloved operation.
The Glock 47 retains the Gen5 design philosophy but introduces modularity by allowing compatibility with Glock 19 slides and other components. This makes it versatile for law enforcement professionals who may require adaptable configurations.
Even though its slightly shorter slide compared to the Glock 17, the Glock 47 maintains a balanced feel that suits both concealed carry and open carry setups.
Caliber & Barrel Length
Both models are chambered in 9x19mm, making them compatible with widely available ammunition suited for training, self-defense, and duty applications. The Glock 17 has a barrel length of 4.49 inches, providing enhanced muzzle velocity and accuracy at extended ranges—ideal for precision-focused scenarios like competition or tactical drills.
The Glock 47 also uses a Marksman Barrel but measures slightly shorter at approximately 4.38 inches due to its compact slide design. While this reduces overall length for better maneuverability in confined spaces or IWB (inside-the-waistband) holsters, it still delivers consistent shot placement up to moderate distances.
Capacity & Magazine Options
Standard capacity is identical across both models at 17+1 rounds using factory magazines. Extended options include the OEM 24-round magazine or even the high-capacity drum mags favored by range enthusiasts for prolonged practice sessions without frequent reloads.
Magazine interchangeability is another advantage of these pistols. The Glock 47’s modularity allows seamless use of magazines from other Gen5 platforms like the Glock 19X or G45, which simplifies logistics if you own multiple firearms within the same family.
Trigger Performance & Safety Features
Both pistols feature the Gen5 trigger system with an improved pull weight averaging around five pounds out-of-the-box. This provides predictable break points suitable for new gun owners while maintaining responsiveness appreciated by experienced shooters during rapid engagements.
Safety mechanisms include a trigger safety tab, firing pin safety block, and drop safety system designed to prevent accidental discharge if dropped—a critical consideration for law enforcement officers carrying OWB (outside-the-waistband) on patrol or civilians relying on appendix carry positions during daily activities.
Shooting Performance in the Field
Accuracy & Grouping
The Glock 17 and Glock 47 both deliver consistent accuracy, but their designs cater to different shooting preferences. The Glock 17's full-size frame and longer barrel (4.49 inches) provide a slight edge in precision during extended-range engagements or competitive shooting scenarios.
This makes it ideal for law enforcement officers or enthusiasts prioritizing tight groupings at distances beyond 25 yards.
The Glock 47, with its slightly shorter barrel (4.38 inches), balances accuracy with maneuverability. While its grouping performance remains reliable within standard defensive ranges of up to 15-20 yards, it may not match the pinpoint precision of the Glock 17 over longer distances.
But, the improved Marksman Barrel on both models ensures enhanced rifling for consistent shot placement regardless of ammunition type.
Reliability & Durability
Both pistols excel in reliability under various conditions, making them trusted choices for duty use and personal defense. The Glock 17 has a long-standing reputation for enduring harsh environments without compromising functionality.
Its proven track record includes military deployments and high-volume training sessions where dirt, debris, and moisture are common challenges.
The Glock 47 incorporates Gen5 upgrades like an nDLC finish on critical components and ambidextrous controls that enhance durability while maintaining compatibility with other Gen5 parts.
These features make it versatile for users who frequently switch between roles or require modularity across multiple firearms platforms. Both models perform well with factory magazines, reducing feed issues even during rapid-fire drills or adverse weather conditions.
Recoil and Handling for Different Use Cases
Recoil management differs slightly due to variations in weight distribution and slide length. The Glock 17’s larger frame absorbs recoil more effectively during sustained fire, providing better control for shooters engaging targets rapidly or transitioning between multiple threats.
This advantage benefits competitive shooters using OWB holsters or law enforcement professionals needing superior handling in dynamic situations.
The Glock 47 offers comparable recoil control but emphasizes versatility through its compact design elements. It pairs well with IWB or appendix carry setups while retaining enough mass to mitigate muzzle rise during defensive encounters at close range.
For concealed carriers seeking balance between comfort and shootability, the Glock 47 provides practical advantages without sacrificing performance essentials like follow-up shot speed or target reacquisition efficiency.
Concealed Carry & Practical Use
Comfort for Daily Carry
The Glock 17 and Glock 47 differ in how they accommodate daily concealed carry. The Glock 17, with its full-size frame and 7.95-inch overall length, may feel bulkier when carried inside the waistband (IWB) or appendix positions.
Its larger grip can print more noticeably under light clothing, making it less discreet for everyday use unless paired with a high-quality holster.
In contrast, the Glock 47 offers improved versatility due to its modular design and slightly shorter barrel at 4.38 inches. This reduction enhances comfort during extended wear while maintaining compatibility with compact setups using Glock 19 slides or frames.
For concealed carriers prioritizing adaptability, this feature simplifies transitioning between roles such as off-duty carry or plainclothes assignments. Pairing either model with a sturdy IWB or OWB holster ensures secure retention and minimizes discomfort during prolonged periods of wear.
Draw Speed & Accessibility
Both models support efficient draw speeds when paired with proper training and ergonomic holsters. The Glock 17’s longer grip provides a consistent purchase, aiding quick draws from OWB rigs commonly used by law enforcement professionals or competitive shooters in duty scenarios.
But, its size may require additional adjustments for concealment-focused users aiming to reduce printing without sacrificing accessibility.
The Glock 47 balances accessibility with reduced dimensions that cater to concealed carry needs while retaining a standard magazine capacity of 17+1 rounds. Its ambidextrous slide stop levers further enhance usability for left-handed shooters or those practicing unconventional shooting stances during defensive drills.
Selecting compatible holsters—such as appendix-carry options for rapid access—optimizes performance in real-world situations where speed is critical, like home defense or close-quarters engagements.
