.45 Automatic Colt Pistol (also known in some countries as the 11.65x23 mm), and no other cartridge.
The original Colt 45 (1873) was a single action pistol with a revolving chamber that held 6 rounds. Single action meant that the hammer had to be cocked before pulling the trigger or, in other words, the trigger simply released the hammer, it did not arm it as well, as in the case of a double action pistol. This is why you would often see the cowboy (Roy Rogers, for instance) madly fanning the hammer of his Colt with the palm of his hand while holding the trigger with the other, to effect rapid fire of several rounds. It does not, however, explain how they could fire so many shots without reloading.
The Hi-Point Model JHP .45 ACP magazine typically holds 9 rounds of ammunition.
You can shoot 45 Long Colt or .410 shot shells with this weapon. 45 ACP rounds will not work properly.
It could be any pistol chambered for one of the several handgun calibers in the .45 family. The most famous .45 handguns are actually chambered for different rounds. The Colt model 1873 "Peacemaker" was offered in .45 Colt or "Long Colt" caliber, among other calibers. And the famous Colt model 1911 was sold in a caliber called .45 ACP (automatic Colt pistol). The .45 ACP is not interchangeable with the .45 Long Colt, but they both fire big heavy bullets at similar velocities.
The Colt M1911 and the colt M1911A has only 1 caliber .45 or 45/100 of an inch. This round is also known as the colt .45 A.C.P. (all Colt pistols) It is a short round which differs from the .45 long round.
No, it isn't. You won't get proper headspacing, and the end result could be catastrophic.
