The .45 GAP was developed by an engineer with CCI/Speer, commissioned by Glock, to be a smaller round with the same power as a .45ACP. This was achieved essentially with powder selection. The .45 GAP has the same diameter as the .45 ACP but the case is shorter, it uses small pistol primers, and is designed for higher standard pressure to make it on par with the terminal velocity of the .45ACP round. To compensate for this increase in pressure the round has a stronger case head to prevent case head blowouts. The .45 GAP stands for "Glock Automatic Pistol" and is the first cartridge associated exclusively with Glock. The .45 GAP and the .45ACP are completely different rounds that are not interchangeable, although they perform similarly.

The .45 GAP is a shorter cartridge than the .45 ACP. Developed for the Glock Automatic Pistol (that's the GAP) it does not interchange with the .45 Colt Automatic Pistol (ACP). Made for a smaller firearm, shorter action, etc.

ACP means Automatic Colt Pistol. .45 ACP and .45 Auto are the same cartridge. .45 Colt and .45 Auto Rim are a revolver cartridge. .45 GAP (Glock Auto Pistol) is a shorter round than the ACP, and does not interchange with it.

Can ammo that does not say acp be used in a hand gun that says acp n gun?

Yes- IF IT IS THE CORECT CARTRIDGE. .45 ACP (Automatic Colt Pistol) may also be known as .45 Auto. It is NOT the same cartridge as .45 GAP (Glock Auto Pistol) or .45 Colt (revolver cartridge).

What's the difference between 45 ACP and 45 GAP ammunition?

The .45 GAP (Glock Auto Pistol) round was designed by CCI / Speer, at the request of Glock, to provide a cartridge that would rival the firepower of the .45 ACP, but would be shorter to fit in a more compact semi-auto pistol. The .45 GAP round is the newest pistol round to be backed by a major firearms producer, Glock. Due to it's new-ness the only pistols to fire it are the Glock 37, 38 and 39. For the practical shooter, the .45 GAP might not be the best choice, due to ammo availability and the somewhat specialized nature of the round. Most .45 enthusiasts choose the .45 ACP. The .45 GAP is sort of like the DeLorean of the pistol ammo world. New, cool, and slightly exotic, but not mainstream and somewhat hard to come by. Muzzle velocity for the .45 GAP is 880 ft / sec to 1,000 ft / sec, and impact energy is 395 ft lbs to 411 ft lbs.
