The "New Service 45 Colt" marking can either mean 45 Long Colt or 45 ACP, although the latter have a shorter cylinder and are extremely rare. Any gunsmith can verify the chamber length. There is no such thing as a 45 long colt it's a 45 colt . The 45 colt ACP is for a auto pistol . If your colt uses 45 APC it will need moon clips. But on the other hand they have a rimmed 45 APC now where you don't need moon clips. Take it to a Gunsmith. Unless the barrel is marked '.45 ACP' or '45 Auto Rim,' it's chambered for the standard .45 Colt cartridge. The mark will be '.45 Colt Ctg' or something very similar. Post-1917 New Service Colts factory-chambered for .45 ACP are rare, but certain 'shadetree gunsmiths' may have altered the chambering. That would involve changing the cylinder stop, the pawl, and the cylinder. TexasCharley -- Correct Markings -- If you have the 1926 patent date, you have a late commercial New Service. As mentioned above, chambering in .45 ACP was rare that late but barrel markings would be the same as the Commercial 1917: .45 AUTO. CTGE. If your gun is marked on the left side of the barrel: .45 COLT, then that is what it is chambered for unless it has been altered (although FAR more .45 ACP revolvers were altered than the other way around). Any gunsmith can mike the chamber and tell immediately. email@example.com
Danger,Do not attempt this!.
Although it can be done, DO NOT !! Never fire ammunition in a weapon that it is not chambered for.
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.
Maybe. You need to figure out which .38 your Colt is chambered in. .38 Short Colt and .38 Long Colt guns will not chamber a .38 Special. .38 Colt Special is the same as regular .38 Special. If you cannot tell which caliber it is you need to take it to a gunsmith and have him tell you.
Here is your answer : The gun is a Colt Frontier Scout, chambered in 22 long rifle. It is a commemorative for General Nathan Bedford Forrest. There were 3000 of these pistols made in 1969.

No. .38 Long Colt was the forerunner to .38 Special- and was originally a black powder cartridge. The .38 Special is more powerful- the .357 magnum is MUCH more powerful. Neither the Special nor the magnum should be fired in a gun chambered for .38 Long Colt. This is VERY dangerous.
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.
The chambered nautilus has existed virtually unchanged for 500 million years.
