Glock 45: Is This the Best Glock Gun of Them All?
The Pentagon’s quest for a new handgun ended in the U.S. Army choosing one handgun, the Sig Sauer P320, to replace the Beretta M9 across the entire armed forces. Although most companies lost, the competition encouraged many companies to enter modified designs that otherwise might never have seen the light of day—designs that are now hitting the civilian market. The Glock 45 pistol is one such design, incorporating a compact slide with a full-size frame to produce a pistol unlike other Glocks.
The U.S. Army’s Modular Handgun System competition saw eight different gun manufacturers in the U.S. and Europe scramble to produce a pistol that fit the service’s requirements. These guns ranged from a modified version of the military’s M9 pistol, the Beretta M9A3, to the Smith & Wesson M&P9. Handgun technology had changed dramatically since the M9 had been picked in the late 1980s, with the use of polymers, improved ergonomics, and other features now standard on civilian pistols. The Army, which oversaw the MHS tests, expected to fully exploit these new technologies in the new pistol.
