I have decided to sell my 4" PC 625-8 made or shipped in 2002 according to the fired case envelope. This gun is serial KCB00XX has the lock but forged parts, all the docs, demooner & clips, the wax paper and the Performance center aluminum case ,original laminated gray green grips,quick change gold bead front sight. gun has about 125 rounds thru it and is super tight. what do you think it is worth?
