My tuned up and customized Pro Carry II 9mm. Kimber SS slide stop, ambi thumb safety, grip safety, and tactical night sights. Wilson Combat firing pin, extractor, mainspring housing/magwell. Cylinder&Slide hammer group and Nowlin extended mag release.
And my PT1911, complete rebuild. Only Taurus parts left are the slide and frame, mostly Ed Brown-barrel/bushing, trigger, mainspring housing, guide rod, grip safety, Hardcore firing pin, and extractor. Cylinder&Slide hammer group. Wilson Combat springs, extended slide stop and thumb safety. Nowlin extended mag release, and Novaks fiber sights.
I may have forgotten a few items on these pistols, but the important stuff is there. For what I invested in tools and parts and the original cost of the guns, I probably could have bought 3 high end 1911's. But the experience was well worth it, and I have everything I'll ever need to work on or build another 1911.
