It depends. The term "45 rounds" can refer to any 45, and all 45s are not interchangeable. However, I would say that when people say 45, they usually mean 45 ACP.
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.
several different ones do. The most common is the 1911-A1 45 Auto
Both. .45 Auto and .45 ACP are the same round.
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.
You can shoot 45 Long Colt or .410 shot shells with this weapon. 45 ACP rounds will not work properly.
The Hi-Point Model JHP .45 ACP magazine typically holds 9 rounds of ammunition.
.45 auto and .45ACP are the same round.
Choosing the best weapon for self defense is a matter of personal preference. The .45 ACP is generally considered a very good defense weapon. There are very few handguns that shoot a larger projectile, but bullet size is a trade off with capacity (how many rounds a pistol can hold). Typically, a .45 ACP pistol holds 7-8 rounds, compared to a 9mm's 14 rounds or more. If one is expecting to be in a prolonged gun fight, one might prefer having more rounds.
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.
Nothing, two names for the same round.
about the same. about 850 ft. per second................
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.
