Another vote for the 1911 conversion. I have a Kimber .22 Conv. on a 1911, I built,(top) on a Caspian Frame and slide. THe acxtual Ser # is "Patriot40". Btw, 2 of JMB finest...lol
Btw I also have a .22 Conversion on my DPMS Panther, .223. I use it all the time on the Homestead, to dispatch squirrels to 150lb Goats. took about 10 head shots to take down a 800lb pig. It's just a bolt change out and Black Dog makes mags that fit right in.
