Notes
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.
Background
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.
