The .45 GAP (Glock Auto Pistol) or .45 Glock (11.43×19mmRB) is a
Development
The .45 GAP has the same diameter as the .45 ACP pistol cartridge but is slightly shorter, and uses a small-pistol primer instead of the large-pistol primer most commonly used in .45 ACP ammunition. Originally, the maximum bullet weight of the .45 GAP was 200 grains (13 g). In order to provide terminal ballistics that matched the standard 230-grain (15 g) .45 ACP loads, the .45 GAP was designed to operate at a higher standard pressure—roughly equivalent to the higher pressures found in .45 ACP "+P" rounds. Since the .45 GAP has a much smaller cartridge volume than the .45 ACP, the desired pressure and resulting velocity needed to be achieved through powder selection alone. Later development concluded that the .45 GAP can also fire 230-grain (15 g) projectiles, as does the .45 ACP; though this pushes the .45 GAP cartridge to its limits.[citation needed]

Other .45 GAP firearms
Initially, due to its acceptance by law enforcement and the popularity of subcompact handguns for concealed carry, a small number of manufacturers decided to produce pistols that were chambered in .45 GAP, but they no longer produce any pistols in that caliber. Only Glock continues to manufacture pistols in the .45 GAP cartridge. Springfield Armory, Inc. did make the XD series in .45 GAP, and indeed it was the first commercially available pistol for it, but discontinued that chambering soon thereafter.
Law enforcement applications
Modern law enforcement as a whole has moved away from .45 caliber weapons in favor of firearms chambered in
The Pennsylvania State Police also carried the Glock 37 from 2007, but, due to ammunition supply problems, replaced them in 2013 with the fourth generation Glock 21 in .45 ACP. After recall issues with the new fourth generation Glocks, the Pennsylvania State Police switched to the SIG Sauer P227 in .45 ACP.[3]
