You have a PM with my phone number. I'm going to go shooting in a couple days when my smith gets done with my bugs.
I'll have my 1911 with me. It started a long time ago in a land far away as a RIA 1911. The only original parts are the firing pin, strike plate, slide, barel, bushing, barrel link and pin, frame. Every other part on the gun has been replaced. You shoot mine, and you will be convinced you won't find anything better under 1400 bucks.
Knowing what I know now it would be 800 bucks to get it built right from day one. Maybe a little less. For that matter I'm getting my bugs from the guy that built my 1911 so if you wanted to tag along and meet him that would be fine.
