so i'm having these problems that are about to push me over the edge. santa arrived with the anticipated mini mill, so after having fabricated a steel clone of the plastic mag catch it was time for reassembly. while i was at it i was planning to also insert the updated hammer block that keltec had sent me awhile back.
the good news is that the catch went in without a hitch and is working great. however...
1) while installing the hammer block into the grip was fairly easy thanks to the tips on this site, i simply cannot get the new hammer block to function in the gun. i push the hammer block forward with a thin screwdriver while seating the receiver in the grip, holding the hammer backwards with my thumb. the receiver lines up nicely and the hammer and the hammer block seem to connect properly with the hammer at about a 45 degree angle. however, when i pull the trigger while "simulating" an engaged hammer spring by pushing the hammer forward with my finger, the hammer moves backwards until it breaks, then travel forwards until it reaches the 45 degree angle position where it suddenly locks up! granted that i have not tried to actually install the hammer spring and slide to verify the problem, but i just cant see how the hammer would be able to strike the firing pin when it locks up that early. when i install the original hammer block all is good and the hammer moves *much* further - far enough to hit the firing pin. does anyone knwo what i could be missing?
2) after giving up on the new hammer block i put the gun back together with the original hammer block and tested it. at first all seemed good but after awhile i'd notice that occasionally the trigger would not break - i'd pull it so far back that it would contact the grip, but still not break. since then this problems seem to have gotten worse. some googleing has indicated that this can be due to the pin inside the trigger being loose. i've tried pushing on the pin witht the my finger nail but it doesnt seem to move. just how much force is typically needed if it has worked itself loose? any other known causes of this problem?
