....and am pleased to announce that all the parts were easy to install ! I was pleasantly surprised because I thought all along there was going to be some minor fitting like the little packages said. I installed a Bulletproof extractor, Bulletproof firing pin stop, and a Bulletproof slidestop-all blue, all 70 series on the bottom pistol in the picture (as if you didn't know which one the Operator is..). The parts fit nice and perfectly snug. Shot 100 rounds and everything worked great!
I asked for
Hobbs5624's (what a guy!) advice on which MIM part I should replace because it was giving me worries as far as reliability ( the pistol is my daily carry). Thanks John!
Kudos to Wilson Combat as well. Ordered evening of the 18th and got it afternoon of the 21st (today).
