Ok, I know this sounds like a bit of an oxymoron, but I'm looking to build a budget yet well performing 1911. Now I know I could just buy cheaper but I just like making things myself. I've done my research but I'm looking for a bit of humam input. My question is this: What elements of the firearm are the most critical to its function and feel? As in, where should one spend, and where could one skimp? My gut tells me critical elements would include sear, extractor, barrel and bushing fit. Less critical (could get a cheaper one that works just as well) includes firing pin, mag release, recoil spring mechanism, main spring housing and spring. Is there anything I'm missing or need to focus on (or just plain wrong about?) And finally, for those all so critical parts, anyone have any personal suggestions?
