Does anybody know an up to date source of J-Frame schematics? the manual that I downloaded from S&W still has the old Hammer Mounted firing pin and no ILS schematics. The Jerry Kuhnhausen book and the AGI DVD also use the out of date schematics. I had to take apart my 640 to use as a guide to work on my 642 yesterday. Also, neither Numrich,Brownells or S&W list part numbers for the firing pin assembly or ILS. Help! Does the S&W Parts Manual CD have the new schematics. I'll buy it if it does but I don't need duplicates of the same wrong schematics.
