History of 45 GAP Ammo

In 2003, .45 Glock Automatic Pistol (GAP) ammunition was introduced as the first cartridge to have the Glock name attached to it. Designed as a rimless, straight-walled round, the .45 GAP shares the same bullet diameter as the popular .45 Automatic Colt Pistol (ACP), a hefty .451 inch. For the .45 GAP, the bullet sits in a .755-inch casing (the same length as a 9mm case), giving the ammunition an overall length of 1.070 inches.

Although it’s a big-bore bullet, the ammo uses a small pistol primer with a maximum pressure of 23,000 pounds per square inch (psi), making it a great option for self-defense.

    I'm in no way an expert but I've fired 100 rounds of this ammo so far and am pleased with my purchase 4 inch grouping at 10 yards with my glock 37 which isn't bad for a 45. The ammo does smoke a little but there were no misfires, jams or duds.
