You’ll find the slide and barrel are constructed from high-grade steel, with the barrel featuring an octagonal rifling pattern. The polymer grip frame helps reduce overall weight, while the steel components maintain durability and function.
White dot and outline sights complete the construction.
Chambered In
The Glock 39 chambers the .45 G.A.P. (Glock Automatic Pistol) cartridge, a round that delivers .45 ACP-like ballistic performance in a more compact package.
GLOCK’s subcompact model combines ultimate concealment with .451 diameter bullet effectiveness. The design parameters of GLOCK’s platform ensure compatibility with Glock 26/27/33 accessories while maintaining the performance characteristics you’ll expect.
This pistol performs well with experienced shooters, featuring a 6+1 capacity within the parameters of GLOCK’s subcompact framework.
Capacity
Standard capacity configuration of the Glock 39 provides 6+1 rounds of .45 G.A.P. ammunition, with optional 8 and 10-round magazines available for extended firepower.
While this capacity is lower than GLOCK’s subcompact models like the 26/27/33 series, which feature 10+1 rounds, you can compensate for the reduced round count by carrying supplemental magazines. The trade-off reflects the pistol’s ultra-compact dimensions optimized for concealment.
Trigger Pull
Moving beyond magazine specifications, precise trigger control defines the Glock 39’s shooting characteristics.
You’ll find GLOCK’s safe action trigger system delivers a consistent 5.5-pound pull weight across 0.49 inches of travel. The design parameters of GLOCK’s trigger mechanism incorporate an integrated trigger safety, preventing unintentional discharge while maintaining a smooth, constant operating system for enhanced accuracy during fire.
Safety?
Safety features integrated into the Glock 39 exemplify GLOCK’s proven three-tier protection system. Like other GLOCK’s subcompact models, this .45 GAP pistol incorporates a trigger safety, firing pin safety, and drop safety mechanism.
For shooters who want perfection, the design parameters of GLOCK’s safe action system ensure the highest ratings in reliability. With only 35 parts, this Semi Auto delivers the best customer experience through simplified operation.
Action
The Glock 39’s action employs a short recoil, striker-fired system that’s built around the proven Safe Action® operating principle. You’ll find GLOCK’s design parameters fully realized in its double-action trigger mechanism, featuring a 5.5-pound pull weight and 0.49-inch travel distance.
The pistol’s mechanical operation integrates just 35 components, adhering to GLOCK’s core engineering philosophy of reliability through simplicity.
Optic Ready?
Unlike its mechanical design simplicity, mounting optics on a Glock 39 requires significant modification. GLOCK’s factory configuration doesn’t include slide cuts or mounting provisions for red dot sights. You’ll need professional milling work to add optic compatibility, which could impact resale value.
The standard sight configuration remains traditional, without any factory options for direct optic mounting. Custom modification is your only path to red dot capability.
Review
You’ll find the Glock 39’s reliability matches Glock’s legendary standards, with the pistol handling continuous firing cycles without malfunctions while delivering .45-caliber stopping power in a concealable package. The subcompact’s manageable recoil impulse and 6+1 capacity offer a practical balance between portability and defensive capability, though you’ll need to factor in the limited commercial availability of .45 G.A.P. ammunition.
The pistol’s reduced slide mass compared to .45 ACP models contributes to faster sight recovery between shots, while maintaining the proven Glock striker-fired operating system that’s trusted by law enforcement worldwide.
Pros
Designed for concealed carry applications, Glock’s Model 39 delivers several compelling advantages that make it stand out in the subcompact market. You’ll benefit from its compatibility with other GLOCK’s subcompact models’ accessories while enjoying reduced recoil in the .45 G.A.P. platform.

The subcompact design incorporates a 3.43-inch barrel length with a 6+1 round capacity. You’ll find it delivers .45 caliber ballistic performance while maintaining manageable recoil characteristics through its optimized slide mass and spring rate configuration.
Why Is the Glock 19 Illegal?
Like the trusty sidearms that won the West, the Glock 19 isn’t actually illegal at all. You’ll find it’s one of the most popular 9mm striker-fired pistols in the civilian market, completely legal in most U.S. jurisdictions.
The G19’s 15-round standard capacity magazine may face restrictions in certain states like California or New York, but the pistol itself is perfectly legal when purchased through proper channels with appropriate permits where required.
What GLOCK Do Navy Seals Carry?
Navy SEALs primarily carry the Glock 19 and Glock 45 as their standard-issue sidearms. You’ll find that military preference favors these 9mm platforms for their proven reliability in extreme conditions.
The G19’s compact frame offers a 15-round capacity, while the G45 combines the G17’s full-size grip with a G19’s slide length. Both pistols feature striker-fired mechanisms, polymer frames, and enhanced reliability under maritime operations.
Can a Glock 39 Shoot a 45 ACP?
You’d bet your life on proper ammo choice, and here’s why: No, you absolutely can’t shoot .45 ACP in a Glock 39. These are incompatible calibers despite sharing the same bullet diameter.
While both use .451″ projectiles, the G39’s chamber is specifically engineered for the shorter .45 G.A.P. cartridge case. Attempting to fire .45 ACP could cause catastrophic failure, damage your firearm’s action, and create dangerous overpressure conditions. Stick to .45 G.A.P. ammunition only.
