Light strikes

484 Views 4 Replies 4 Participants Last post by  edd_browne
Since I am a new member I hope that I am not going over old ground. I picked up a used 1gen P3AT from a local gunsmith (Tucson). At first I had no problems, in fact the accuracy of this little gun was amazing. However, as I went on I began to get light strikes. There was a definite mark on the primer but a failure to fire. I fired about 5o rounds and had this happen first once per magazine and eventuall every round in the magazine failed to fire. I have been polishing and doing the pencil test (about 3 inches past the muzzle). Anyone got any suggestions? I am handy and do most of my own repairs.
Thanks for you help

What kind of ammo? Have you detail stripped the slide and cleaned it out really well?
welcome to KTOG

you MUST release the trigger completely. IF you release it partial and pull, the hammer just drops. enought to dent primer but not fire. this is the normal quirt of the KT trigger and refered to as short stroking trigger. you must rack the slide to reset the trigger.

if you are not short stroking, it could be a dirty firing pin. since it is used, it might be the hammer spring is weak from past owner stretching it during disassembly
Thanks for the replies. The ammo that I was using was range reloads. I have since purchased three different brands to try out. I think that the problem may be that I didn't let the trigger go all the way back. The range is on my schedule for later in the week and I'll try tall your suggestions.
If I still have problems I'll take a shot at replacing the springs as suggested.
If the cause is the trigger not resetting, KT will replace the hammer block.

You can also remove the firing pin to check for burrs and crud.
(let some penetrating oil soak into the set screw first, or the socket could strip)

Also, look at the point of the firing pin.
If it was not tapered properly, it could be too wide.
