Glock G41 Gen4 MOS

About the Glock G41 Gen4 MOS

The Glock G41 Gen4 MOS is a semi-automatic pistol chambered in .45 ACP, produced by Glock Ges.m.b.H. since 2015. 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 13-round magazine capacity, this pistol offers adequate firepower for defensive carry. 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 5.3-inch barrel maximizes accuracy potential and ballistic performance, making this an excellent choice for target shooting, competition, or field use. Weighing 767g (27.1 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 G41 Gen4 MOS was Glock's acknowledgment that even .45 ACP competition shooters were embracing the red dot revolution. In IDPA's Custom Defensive Pistol division, the G41 MOS offered something no 1911 could match without expensive custom slide milling: a factory optics-ready .45 with 13+1 capacity and Glock reliability. While the .45 ACP competition market has shrunk, the G41 MOS remains the only factory optics-ready competition .45 from a major manufacturer.

Glock G41 Gen4 MOS specifications

The G41 Gen4 MOS uses the same adapter plate system as other Gen4 MOS models, supporting Trijicon RMR, Leupold DeltaPoint Pro, C-More STS, and other popular optics footprints. The MOS variant adds minimal weight (approximately 2 grams for the machined optic cut and cover plate). The G41 MOS remains Gen4 only -- no Gen5 version has been produced, making it one of the few Glock models still exclusively in Gen4 configuration. This reflects the niche nature of the .45 ACP competition market.
