Colt Revolver Question

    What was the model number of a Colt that would fire Long Colt, rimmed .45 and ACP. I have read that the rimmed .45 can be fired in the Long Colt revolvers will the length of the cylinder cause the accuracy of the weapon to be poor.

    I think you need two cylinders. One for the 45 Colt and one for the 45 Auto Rim or 45 ACP with "half moon" clips if you want them to extract with the ejector rod. There are now full moom and 1/3 moon. A long jump to the rifling is not conductive to accuracy.

    The Model 1917 that they made for the U.S. military during the First World War, could fire 45 ACP on 3 round clips, or 45 Auto Rim cartridges. Because of the rim thickness, and use of the 3 round clips, of both these cartridges. The headspace was substantially greater then the 45 LC, it wasn't possible to also fire that cartridge.

    Some enterprising aftermarket gunsmiths after the war tried to fit the Colt with an auxiliary cylinder for the 45 LC. This was a delicate operation because the cylinder stop on the frame had to be altered to accommodate and function correctly with both cylinders. Unless the gunsmith was a pro and knew what he was doing, didn't always work out.

    I know you ask about a COLT however you may be thinking about the S&W model 25. For the most part S&W model numbers are for chambering for one cartridge only. However the model 25 came in one configuration for 45ACP and 45Auto Rim but also came in another configuration for 45long colt. The model number was the same but you could not interchange ammo between the two.

    I know of no revolver that will shoot all three of .45 ACP, .45 AR, and .45 Colt without changing cylinders.
    Any of the .45 ACP double action revolvers back to 1917 will handle .45 AR, that is what it is made for.
    It is possible to gunsmith a .45 Colt double action revolver to shoot .45 ACP without losing .45 Colt capability.

    Yes, not only the M1917 model, but also the Colt New Service. I have a New Service in .45 ACP; I use full-moon clips with it. It is a very nice shooting revolver.
