I have Colt SAA's and USFA SAA's. USFA makes a better Colt than Colt does. They do them on CNC equipment in the old Colt factory under the blue dome in Hartford, CT. I even had one of their custom made Lightning rifles with Turkish walnut stock for a few years. It was nice but hard to load the .45 Colt rounds. Had to start using a push stick rather than tear up my thumb and thumb nail all the time. It's just the way they were designed way back when.
Thanks for the kudos.
The frame(at least this one) wasn't case hardened.
DakotaDoc, I toured the USFA factory last year with Ray Phillips and Doug Donnelly (President of USFA) and it wasn't at the old Colt factory then. I didn't know they moved.
