I can't say if my 1911 9MM Pro has been touched by a PC smith but I have never felt a slide to frame fit that was as solid and smooth as my gun, If this is production line work than PC work must be unbelievable.

PS I also would like to add that the fired case that came with my pistol was from Dec. 5 months before the gun was officially released. So my gun was either a SHOT show sample or a bonus for a dealer. I don't think my gun was made on the regular line because of its date. This is just a guess on my part.
