usually a cheaper way to go is just to get a decent top end for your 1911 bottom- get a commander and you can get 5 calibers out of it- 22, 9, 38 super, cor-bon 40, 38/45 clerke, and 45 acp
as long as the barrels are ramped on all of them, you won't have feeding issues
I think my current game plan is a previously enjoyed 1911 from a reputable manufacturer. Probably a 1911 in .22lr after that. Or a Sig p220, lol.
I had a Kimber 22 conversion for my Kimber TLE/RL2, never wasted my time with it at the range. So sold it
