45 GAP (Glock Automatic Pistol) Ammo For Sale

45 GAP (Glock Automatic Pistol) Ammo For Sale. .45 GAP ammo (GAP is an acronym for Glock Automatic Pistol) is a rimless, straight-walled,.451 caliber, pistol cartridge developed by CCI/Speer engineer Ernest Durham at the request of firearms manufacturer Glock for use in their model 37 semi-automatic pistol to create a pistol cartridge with the same power as the.45 A.C.P (Automatic Colt Pistol) but which could be fired from a 45 GAP ammunition was the first commercially produced cartridge associated with Glock. The design concept of equal power from a reduced capacity case was achieved by reinforcing the web of the case to prevent blowouts and selecting a modern powder to produce a cartridge with an internal chamber pressure roughly equivalent to that of.45 ACP +P loads.

Although the initial round used a 200-grain bullet, it was subsequently established that the new cartridge could also be loaded safely with 230-grain bullets; nevertheless, the muzzle velocity and terminal ballistics of this bullet weight are inferior to the same bullet fired from a.45 ACP cartridge. In contrast, factory loads for this cartridge are now available with 165 grain and 185 grain hollow point bullets in addition to the original 200 grain and 230 grain FMJ bullets, and Magtech provides a 165 grain frangible bullet for this cartridge. Therefore, the.45 G.A.P. cartridge provides the terminal performance of a.45 caliber bullet in a 9mm round for shooters of smaller stature who find the.45 A.C.P. too cumbersome to hold comfortably.
