I made a .22 conversion kit a few years ago for the 1911. It's different from the common ones in that it only replaces the barrel and magazine. Everything else, slide, hammer spring etc. stays the same. I thought it was a pretty cool idea but...is it really? As with any design, there are trade offs. It will probably never be as accurate as a Marvel but as a plinker I think it has some desirable features. I made a video to show it. I don't really have the resources to try to get it in production right now anyway but sometimes wonder if it's worth pursuing even if I did. What do you guys think about the concept?
