Awhile back I picked up the gun you see below (excuse the quality of the pics).
This is a M640 from the Performance Center. SN PCA02xx which S&W tells me was produced 6-8-91. 2 5/8" barrel with the compensator. Smooth rosewood stocks. It is set up identically to the Paxton Quigley model but predates that run by a few years. I see no reference to these in the 2nd or 3rd edition of the SCSW.
Unfortunately it did not come with a box or papers.
What do folks know about this run of guns?
