Caliber question?
Is there any difference in 45AP & 45ACP. I normally see them listed as 45ACP but, I noticed one on an auction, a gun listed as 45AP. So, are they the same cartridge & What is the actual definition of ACP.
Thanks

may be talking about 45GAP=Glock auto pistol. it's just a new phase expensive ammo that i can't really see that much of need for over the 45 acp. Most likely designed so your auto can hold a few more rounds in the mag. this is becoming less of an issue now that Springfield released the XD 45 acp.

ACP=Automatic Colt Pistol. Never heard of 45AP, could it be a typo? Seems like an easy one to make.

I've seen some websites use "AP"when they mean "ACP",for some reason. Such as www.galleryofguns.comthen go to gun locator, start locator.
I'd guess AP means ACP in that auction, though make sure to email the guy to be safe. Assume nothing in a sale unless it's specifically stated.

This is NOT a "caliber" question it is a "CARTRIDGE" question.
When it comes to guns and ammunition it is very very important to be clear and correct in communications.
If you put the wrong ammo in a gun and pull the trigger it may not be "woops! I made a little mistake." it could be "woops! I blew my hand off!"

RE: Caliber question?
There is a cartridge called the .45 AR which stands for auto rimmed. Do you think itshould havebeenan R and not a P. Here is someinfofrom anarticle I found.
1. Back in the '50s, many of us learned to enjoy shooting .45 caliber revolvers. These guns, from the then-modern Model 1955 to the old standby Model 1917, taught us two things. First, that the .45 ACP cartridge could perform well in a sixgun, and second, that we hated loading those auto cartridges into half-moon clips.
That dislike for revolver clips was pretty universal, which is why the Peters Cartridge Co. (now Remington) introduced the .45 Automatic Rimmed. The most remarkable feature of the cartridge was the very thick rim, which was required to fill the larger space between cylinder and breech face. This is much larger in .45 ACP revolvers than in normal rimmed cartridges, because of the relationship of the rim to the clip.
Back in those days, you could only get brass by shooting factory ammo. Today, you can't get factory ammo, but brass is plentiful. It is made by Remington and available from companies, such as Midway USA, that sell bulk brass. So the .45 Auto Rim is almost exclusively the handloader's province.
Half a century ago, there was but one factory load: a 230 gr. Lead Round Nose at a velocity of about 800 fps. (For a short time, there was also a load using a 230 gr. FMJ at about the same speed.)
The Auto Rim can be loaded using standard .45 ACP dies, although you will need a different shell holder. Any bullet that can be used in the .45 ACP can be used in the Auto Rim, but there really is no need to use jacketed bullets here. There aren't very many people who carry .45 revolvers for defense these days, but if someone does, they can surely handload .45 Auto Rim ammo to their heart's delight for practice purposes, then load a few clips of .45 ACP ammo for defensive purposes.
