Grinder, the Performance Center super collector. I started collecting PC pistols after seeing his posts on the forum. I learned a lot from him and also bought a lot from him. One just happen to be a NIB PC 45 CQB all stainless, and another was the TuTone 45 CQB. I have sold the TuTone, but the all stainless is my all time favorite PC 45 and is still NIB. I have been tempted to switch the MIM trigger, hammer & sear for a Flash Chromed spurless hammer and wide 645 trigger with the appropriate sear. I have acquired the parts but need to shoot it before deciding to make the switch. Night sights would be great also.
