Actually, the cartridges are .45 ACP (automatic Colt Pistol) and .45 Colt (the cowboy era revolver cartridge. There is not really a Colt 45 Long. Can a revolver shoot both? Some can- they are chambered for the Colt .45 -but to shoot .45 ACP they need a "half moon clip"- a strip of metal that holds 3 of the shorter .45 ACP cartridges. 2 of those fill a 6 shot revolver. The PISTOL (not revolver) that shoots the .45 ACP cannot shoot the .45 Colt- no groove for the extractor to pull a fired cartridge out of the chamber, and it is too long.
I assume you colt is a single action revolver ????? if so, made about 1888
Depends on the revolver
