Anyone know where I can get an Aluminum 1911 frame for near the price of a steel one? (~$100, Fusion sells them for $230 but I only want to stick a .22 top-end on the frame, not build some slick carry beast...) Thanks.
Sorry, I don't know. I would ask the guys at forum.m1911.org.
They even have a sub-forum for 22 conversion kits.
I have a Marvel Precisioun Unit 1 on a Sprinfield Champion. Very accurate. Much more accurate than me. I still have jams though, weird thing where the round goes in at a weird angle and the case gets crushed by the slide. Maybe I need to break it in a little more. Maybe try some different types of ammo.
