I have been tinkering with 1911's for over 20 years. I could say now that I'm able to service my own 1911's for my intended use. However, I just started shooting cz's. Got a couple of TS' last year and they only needed chamber reaming, so that was easy.
Just got an SP-01, and realized I'm quite tired of tinkering. Don't really have the energy now to even learn a new platform. Got my parts from CGW, and I'm in no hurry to do anything. Maybe in a few months. I plan on changing only the most necessary parts to get down to a sub-4# (single-action) trigger pull, then I'll consider this shootable for myself.
