    the term ".45 auto" is commonly understood to refer to the ammunition cartridge named ".45 Automatic Colt Pistol" which is commonly abbreviated as just ".45 ACP" This cartridge is rimless and used primarily in semi-automatic handguns.

    The term "Colt 45" is unclear.

    There's another ammunition cartridge called ".45 Long Colt" which is often just called "45 Colt" or ".45 LC" But most people don't put the word "Colt" in front of the number 45 when referencing this cartridge. This cartridge has a rim on the base and is used primarily in revolvers.

    If you're referring to a comparison between .45 LC vs .45 ACP ammunition, then no, they are NOT compatible with one another. Some specialized guns such as the Smith & Wesson Governor (a revolver) can shoot both by using moon-clips to hold the .45 ACP cartridge in place, but for most guns the ammo cannot be used interchangeably.

    But since most people don't say "colt 45" in reference to .45 LC ammo, its unclear what you're asking. The term "colt 45" could refer to a gun made by Colt and chambered for any of the several .45 caliber ammunition cartridges.

    The term could refer to a 1911 style semi-auto pistol which DOES use .45 ACP ammo, or it could refer to a revovler made by colt, or even a revovler made by another company but chambered for .45 Long Colt ammo. It could refer to a gun made by Colt chambered for .45-70 or .45 Government ammo.

    So you'll need to clarify what you mean by "colt .45" before we can give more specific information.

    It will work in a Colt model 1911 semiautomatic pistol, but not a Colt Single Action Army revolver.

    Ruger makes a Blackhawk with interchangeable cylinders. One for .45 LC and the other for .45 ACP

      Most any single action revolver has conversion cylinders available, not just the Ruger Blackhawk.

    I do not understand your reference here. If you are looking to use .45 ACP rounds in a revolver chambered for .45 LC or Long Colt, don't. The results will not be what you want.

    In a Colt 1911A1, yes. Yes it does.

    Colt .45 is a malt liquor.

    If you are talking about a gun, then you need to be more specific because Colt produced both the .45 Colt (aka .45 Long Colt) which was developed for the Colt Single Action Army (aka Colt Peacemaker) revolver AND the .45 ACP (aka .45 Auto) for the Colt 1911 (semi-auto pistol).

    And no, the two rounds are not interchangeable.

    I don't know why you would want to put a pistol round into malt liquor.

    The correct name for .45 auto is .45 acp acp stands for automatic colt pistol but many brands started making guns chambered in 45 acp so instead of putting colts name on it they just called it .45 auto .45 colt and .45 auto are the same rounds unless your talking about .45 long colt

    It does in a Ruger with two cylinders. Otherwise, no, you can't use a rimless cartridge in a chamber meant for a rimmed cartridge.

      Tim - .45 Auto and .45 ACP are the same thing, just two different ways to abbreviate the official cartridge name of .45 Automatic Colt Pistol. That's different from .45 Long Colt. I guarantee you're not shooting .45 ACP and .45 LC interchangeably in your $200 hi point.
