Zullo74 posted this in the P11 section http://www.ktog.org/cgi-bin/yabb2/YaBB.pl?num=1207010747 It can be extended to the P32, P3-AT and PF9 with a slight modification. The modification requires removing 1/8" from the Buttonhead screw. Before the naysayers jump on this, I'll give some backing information. I x300 magnified the screw hole and a new firing pin and took pictures on an optical comparator, then magnafluxed the slide and firing pin. I then dry fired it about 500 times. I then x300 magnified and took pictures again and compared them and then magnafluxed the parts again. I found ZERO difference other than a very light polish of the oxide finish on the firing pin where it came into contact will the ball bearing. I did use Blue Loctite on the button head screw. The reason this mod caught my intention was one of the ranges I goto requires you to dry fire your weapon into a trap before the range master will clear you to leave the firing area. This mod eliminates my changing of the screws after every couple of range visits.
