I really like my Marval 22 conversion. Only problem is it's sitting atop my bullseye 1911. I am thinking of buying a Kimber target rimfire for the Marvel and selling the upper. My question is will the Kimber upper work on any other 1911? Somewhere I read that they were made by Ceiner and are identical to the Ciener 22 conversions. the other option is buying a 1911 lower, but that seems to be costlier than the Kimber.
