extended firing pin for j, k ,l n revolvers Looking for some information on extended firing pins for J, K, L, N revolvers. I just got a new to me 625 that had some work done to it including an extended firing pin. It had not been shot since the rework so when I put a load of rounds in with the moon clip the cylinder would not close because the firing pin was extended. Further examination found the the pin was stuck forward and required a hard object and lots of pressure to push it back. A dry fire each time would leave it in the extended position. I replaced it with the normal firing pin which came with the gun thankfully and it seems to work normal. Gun fires well so I may not really need the extended pin as I get a nice deep dimple in the primer. Question for further use is there another company other than Cylinder and slide or did I just get a bad one as can happen. I see no indication of a deformity or burr on it.
