    It's always best to check with the manufacturer.

    Many .22 conversion kits use lighter materials -- for example slides are usually aluminum, or zinc alloy. That's because of the lower power factor of a .22lr wouldn't be able to cycle the heavy 4130 cromoly, or stainless steel, slide of a .45 acp (or even 9mm) specific 1911.

    In fact, I think the barrel of most 1911 .22lr conversion kits don't even have a lug link. They're fixed.

    Therefore even if the .22lr conversion subassembly would accept a .45acp it would probably be pretty dangerous to use ANY parts specifically designed for lower calibers in a higher caliber platform because the tolerances are different.

    This is the pistol but so you would just recommend checking with the manufacturer? would you trust a gun smith or a dealer?!

    Talk with smith and let him/her see what you have.

    Explain in detail what you want. If you agree to have work done, put the exact work to be done in writing.

    If that is a .22 upper on the gun now, you need more parts to make it function in a safe manner.

    You'll need more than just the barrel if you plan on shooting 22lr. My conversion unit includes the barrel, floating chamber, .22 ejector, slide, slide stop, barrel bushing, return spring and a .22lr mag.

    Absolutely...and the OP should be aware that not all 1911 .22lr conversion kits from one manufacturer are totally compatible with another brand of 1911.

    There might be slight fitting issues and, as others have said, it's best to let a gunsmith look at it.
