Have it checked over by a good gunsmith before you attmept this.
a gunsmith needs to check both the ammo and rifle.
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.
DON'T DO THIS UNLESS THE MAKER SAYS IT IS SAFE TO DO SO!!!!!!!!!!!!!!!!
.38 Special. It can also fire .38 Short Colt and .38 Long Colt. Do not attempt to fire .38 S&W from a .38 Special.
No. A .357 Magnum revolver (not an automatic, lever action, or anything else with a headspaced chamber) can fire .38 S&W Special ammo, but not .38 Long Colt.
The pistol fired the .38 Long Colt cartridge, not to be confused with the .38 Smith & Wesson Special (.38 Special), .38 Super, .38 Short Colt, or any other cartridge marked as .38 or .380. That is the only ammunition type which can be fired through this pistol. Current production .38 Long Colt ammo may be run through this pistol. However, I would advise you to have a competent gunsmith inspect the pistol to ensure it is in a condition where it is safe to fire first.
Nope. Matter of fact, you can't even load it. The .45 Automatic Colt Pistol (ACP) cartridge is longer than the .45 Glock Automatic Pistol cartridge (GAP). And the model 37 IS in .45 GAP. Both rounds headspace off the case MOUTH- the .45 ACP is too long for the slide to go into battery (close the action). And, with the exception of some revolvers, you cannot shoot .45 GAP in an .45 ACP firearm.
The same 45 cal. ammo used in the 45 cal. revolver. This can get confusing, there are very different cartridges that are '.45'. In semi-automatic pistol the most common is .45 ACP. The ACP stands for Automatic Colt Pistol, that is the company that developed the cartridge. But for revolvers, you would more commonly use the .45 LC (Long Colt) which is a longer round. Modern Derringer's are more typically a two barrel gun that shoots the revolver cartridge, at least in .45. There are many types and calibers of Derringers that have been made for a very long time. The best thing is to research the specific model of gun you have and get the manufacturers recommendations for ammunition.
DO NOT TRY THIS!!!!!!!!!!!!!!
No
For an extremely long time. It depends upon conditions and ammo type. Civil war explosives are still dangerous.
.45 Long Colt.
