.45 gap is a shorter cartridge and can only be safely fired from a gun chambered for that specific cartridge.
NO, NO, NO, NO, !!!!!!!!!!!!!!!!!!!!!!!!! THEY ARE NOT INTERCHANGEABLE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
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.
No. The 45 ACP (which means 45 Auto) cannot use the .45 GAP or the .45 Magnum.
You can fire a .45 ACP cartridge through a .45 ACP pistol - and only a .45 ACP pistol. The various .45 cartridges (.45 ACP, .45 Long Colt, .45 GAP, etc.) are not interchangeable with each other.
Can't be answered without knowing which 45 you are referring to. 45 ACP, 45 GAP, 45 Long Colt, 45/70 rifle round, 45 blackpowder, etc. and from what type of weapon it is being fired
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.
Nope. Matter of fact, you can't even load it. The .45 Automatic Colt Pistol (ACP) cartridge is longer than the .45 Glock Automatic Pistol cartridge (GAP). And the model 37 IS in .45 GAP. Both rounds headspace off the case MOUTH- the .45 ACP is too long for the slide to go into battery (close the action). And, with the exception of some revolvers, you cannot shoot .45 GAP in an .45 ACP firearm.
Aside from the uncommon .45 GAP chambered Glocks, yes. Check the marking on your barrel for the .45 ACP marking.
Depends on which .45- 45 Colt, 45 ACP, 45 Magnum, 45-70, and which bullet, and what it is fired from. If you mean the .45 ACP fired by a 1911A1 pistol, velocity varies from 830 FPS up to about 1020 fps. Slow, fat, but gets the job done.
No. The .45 Automatic Colt Pistol (ACP) cartridge is longer the the .45 Glock Automatic Pistol (GAP) cartridge. Since they headspace on the MOUTH of the cartridge case, they cannot be interchanged.
The Glock 21 does fire the .45 ACP, as does the Glock 30. You're probably thinking of the Glock 37, 38, and 39, which fire the .45 GAP cartridge - those cannot fire a .45 ACP.
