LIGHT STRIKES A PROBLEM WITH YOUR KEL-TEC PISTOL?
Here's what I do. I turn a #20 HSS drill bit BY HAND
ONLY and draw it in and out of the firing pin tunnel to scrape out any
metal splinters and trash. Then I turn the bit into the firing pin hole
BY HAND ONLY to lightly bevel the edges of the firing pin hole in
the breech face.
Removing this sharp edge reduces the tendency to cut fragments from
the primer when it is slammed against the breech and slides down to
unlock the action. These fragments clog the firing pin hole and
interfere with the strike on the primer. Polishing the pin itself
is good, pay particular attention to the forward edge of the pin head,
that the sharp edge is polished away, and also polish the flat part
that may drag on the setscrew. Polishing the end of the setscrew
doesn't hurt either. Use only light oil on a firing pin, never grease.
I also polish the spring itself by threading it on a small steel
rod and holding it against the wheel, but without a big motorized
buffer wheel this may be more difficult. This may not add much
to reliability, I just do it for good measure. A note of caution,
do not overheat the spring by overbuffing it, you will ruin it.
