Glock G20 Gen5 MOS

About the Glock G20 Gen5 MOS

The Glock G20 Gen5 MOS is a semi-automatic pistol chambered in 10mm Auto, produced by Glock Ges.m.b.H. since 2023. 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 15-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 4.6-inch barrel provides an excellent balance between sight radius and portability, making it equally suitable for duty carry and recreational shooting. Weighing 755g (26.6 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 10mm Auto cartridge has one of the most dramatic origin stories in firearms: Jeff Cooper envisioned it, the ill-fated Bren Ten chambered it first, and the FBI briefly adopted it before deciding the recoil was too much for most agents -- leading to the development of the .40 S&W as a reduced-power compromise. The Glock 20 outlasted them all, becoming the definitive 10mm platform. In Alaska and bear country, the G20 has earned a reputation as the thinking person's bear gun -- lighter than a revolver, holding 15+1 rounds, and delivering enough energy to give pause to a grizzly.

Glock G20 Gen5 MOS specifications

The Glock 20 was originally introduced in 1991 as Glock's first 10mm Auto pistol. The Gen5 MOS variant arrived in 2023 with all standard Gen5 improvements plus the optics-ready MOS slide. Weight without magazine is 755g (26.63 oz), with empty magazine 845g (29.81 oz), and loaded 1100g (38.80 oz). The 10mm Auto cartridge produces roughly 60% more muzzle energy than 9mm Parabellum, giving the G20 genuine capability against large predators. The full-size frame and dual recoil spring assembly help manage the considerable recoil of the 10mm cartridge. Standard capacity is 15 rounds, with 10-round magazines available for restricted jurisdictions.
