ok so im looking into getting a rock island armory 1911.. ive been looking at these for a while... i know there is a variety of 22 conversions ot there but every place i look is always trying them on kimbers or colts... i was wondering if anyone has any experience on the fit and functionality on the RIAs... either that or i need to find if they make a conversion for the SA xd45... id love to own either one..
