Glock 17 Frequently Asked Questions
Q: What is the magazine capacity of a standard Glock 17?
The standard factory magazine capacity for a Glock 17 is 17 rounds. However, restricted-capacity configurations (such as 10-round California-compliant models) are widely available, and the platform can also accept extended factory magazines with 19, 24, 31, or 33-round capacities.
Q: What is the difference between a Glock 17 and a Glock 19?
The Glock 17 is a full-size pistol, while the Glock 19 is a compact model. The G17 has a longer barrel and a taller grip, allowing for a 17-round capacity versus the G19's 15-round capacity.
Q: Can a Glock 17 Gen 6 or Gen 5 use Gen 3 and Gen 4 magazines?
Yes, Glock 17 magazines are backwards compatible. However, if you are a left-handed shooter using the reversible magazine catch on a Gen 4, Gen 5, or Gen 6, you must use magazines with the cutouts on both sides of the magazine body (standard on Gen 4 through Gen 6 mags).
Q: Is the Glock 17 a good choice for concealed carry?
While highly reliable, the Glock 17 is a full-sized firearm, which can make it more difficult to conceal than smaller options like the Glock 19. It is best suited for outside-the-waistband (OWB) carry, duty use, or home defense.
Q: What safety features does the Glock 17 have?
The Glock 17 utilizes the Safe Action System, which consists of three independent mechanical safeties: the trigger safety, the firing pin safety, and the drop safety. There is no external manual thumb safety.
Q: What are the main upgrades on the new Glock 17 Gen 6?
The Gen 6 Glock 17 features an integrated palm swell and built-in extended beavertail, a factory flat-faced trigger for enhanced leverage, a deeper trigger guard undercut, integrated thumb rests, and a direct-to-slide optics mounting system.
Q: How does the Gen 6 optics mount differ from the Gen 5 MOS system?
Unlike the Gen 5 MOS system which sits on top of a thicker factory plate, the Gen 6 utilizes a direct-to-slide mount cutout with lower-profile adapter plates. This design allows red dots to sit lower on the slide, improving durability and enabling a lower co-witness with standard sights.
Q: Are older Glock 17 factory barrels compatible with the Gen 5 or Gen 6?
No. Due to changes in the locking block architecture starting with Gen 5 and continuing into Gen 6, standard replacement barrels from Gen 3 and Gen 4 models will not interchange with Gen 5 or Gen 6 frames.
