Glock G39

About the Glock G39

The Glock G39 is a semi-automatic pistol chambered in .45 GAP, produced by Glock Ges.m.b.H. since 2005. This Austrian-manufactured firearm reflects the engineering traditions and quality standards of its country of origin, designed to meet the demands of both civilian and professional users in a competitive global marketplace. Featuring a 6-round magazine capacity, this pistol offers compact firepower for concealed carry applications. The striker-fired action provides a consistent trigger pull for every shot, simplifying training and reducing the manual of arms - a design philosophy that has become the dominant paradigm in modern defensive handguns. With a 3.4-inch barrel, this firearm prioritizes concealability for everyday carry while still delivering adequate ballistic performance at defensive distances. Weighing 630g (22.2 oz) empty, this firearm strikes a practical balance between manageable carry weight and sufficient mass to moderate felt recoil during shooting. The polymer frame construction reduces weight while providing a textured, ergonomic grip surface designed for secure handling in all conditions. This firearm represents its manufacturer's commitment to delivering a well-engineered, reliable product that serves the needs of discerning shooters seeking quality, accuracy, and dependable performance from a proven platform.

The G39 represents the extreme end of Glock's .45 GAP experiment -- a subcompact pistol firing a proprietary cartridge that never caught on commercially. While the .45 GAP was adopted by several law enforcement agencies, the subcompact G39 remained the least popular of the three models, as most shooters who wanted a subcompact .45 simply chose a .45 ACP platform instead.

Glock G39 specifications

The G39 was introduced alongside the G38 in 2005, completing the .45 GAP model lineup that mirrors Glock's 9mm trio (G17/G19/G26). The subcompact .45 GAP generates significant felt recoil due to the combination of a lightweight polymer frame and the powerful cartridge. Standard capacity is 6 rounds, with 8-round (G38) and 10-round (G37) magazines also compatible. Like all .45 GAP models, the G39 has seen limited commercial adoption due to the niche status of the cartridge.
