Glock 45

About the Glock 45

The Glock 45 is a semi-automatic pistol chambered in 9x19mm Parabellum, produced by Glock Ges.m.b.H. since 2018. 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 17-round magazine capacity, this pistol offers generous firepower for duty use and home defense. 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. The 4.0-inch barrel provides an excellent balance between sight radius and portability, making it equally suitable for duty carry and recreational shooting. Weighing 694g (24.5 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 Glock 45 was born from the Glock 19X, which was Glock's submission to the U.S. Army's Modular Handgun System competition. When the MHS contract went to SIG Sauer, Glock released the crossover concept commercially, first as the coyote-tan 19X and then as the all-black Gen5-featured G45 for the law enforcement market.

Glock 45 specifications

The Glock 45 is the civilian and law enforcement counterpart to the Glock 19X, which was developed for the U.S. Army Modular Handgun System (MHS) competition. Key differences from the 19X include the black nDLC finish (vs. coyote tan), front slide serrations, flared magazine well, and standard Gen5 features. The weight_empty_g of 694g reflects weight with empty magazine per Glock's official specifications; weight without magazine is 616g. The crossover design philosophy provides a full grip for better purchase and control while keeping the shorter slide for easier holstering and indoor maneuverability. Standard magazine capacity is 17 rounds, with optional 19, 24, 31, and 33-round extended magazines available. The G45 MOS variant adds a precision-machined slide cut for direct mounting of reflex optics.
