Glock G40 Gen4 MOS

About the Glock G40 Gen4 MOS

The Glock G40 Gen4 MOS is a semi-automatic pistol chambered in 10mm Auto, 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 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 6.0-inch barrel maximizes accuracy potential and ballistic performance, making this an excellent choice for target shooting, competition, or field use. Weighing 798g (28.1 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 Glock 40 was Glock's answer to the question 'what if we made the biggest, most powerful Glock possible?' With its 6-inch barrel and 10mm Auto chambering, the G40 MOS filled a niche that no other striker-fired polymer pistol occupied: a serious handgun hunting platform. In Alaska and bear country across the Pacific Northwest, the G40 became the go-to sidearm for outdoorsmen who wanted semi-automatic capacity and speed over the traditional revolver. Its combination of 15+1 rounds of full-power 10mm with a red dot optic gave backcountry travelers a defensive option that was both faster to deploy and easier to shoot accurately under stress than a heavy revolver.

Glock G40 Gen4 MOS specifications

The G40 is only available in Gen4 MOS configuration. The 6.02-inch barrel extracts roughly 15% more velocity from 10mm Auto ammunition compared to the standard 4.61-inch G20 barrel, pushing full-power loads past 1,300 fps with 180-grain bullets. The adjustable rear sight allows precise zeroing for longer-range hunting applications. The MOS system is particularly valuable on the G40 since the longer sight radius and hunting application make a red dot optic nearly essential. With hard-cast lead or bonded hollow-point ammunition, the G40 is capable of taking deer-sized game at handgun distances and provides credible defense against large North American predators including black bear.
