So far I have not experienced any problems with my P3AT assembly pin walking out. However I believe in being prepared. I ordered some new assembly pins and they should arrive this week, along with other spare parts and magazines.
I am planning to do the cut and screwdriver slot as described at http://www.1bad69.com/keltec/assemblypin.htm
However I got to wondering if the assembly pin is designed to rotate? I haven't seen this question addressed on any of the Kel Tec sites. I took some laquor thinner, cleaned the grease from the head of my assembly pin and applied a dab of my wife's nail polish to a spot on the edge of the pin. Then I noted the paint spot location and manually cycled a few rounds though. Guess what? The assembly pin rotates about a sixth of a turn CCW with each cycle.
Of course if I slot the pin as described above, the pin will not rotate anymore. Will a few hundred or thousands of rounds banging the barrel against the now frozen assembly pin do any sort of damage? I know the pin in my 1911, Karh Arms, etc. doesn't rotate, but perhaps it's designed differenty?
Could that be the reason Kel Tec won't slot the production assembly pin? Or conversly, could the rotating assembly pin be the reason that problems don't show up until a couple hundred rounds go through the weapon? Seems to me a rotating steel pin in an aluminum hole might not be a good idea.
Anyone have experience with a slotted assembly pin that's had a thousand rounds or more of use? I plan to practice frequently. I believe in shooting a lot.
Keep shooting.http://KTrange.com/phpbb2/images/smiles/icon_confused.gif
