Firing pin difference

brigade · Post by **brigade** » February 8th, 2007, 10:06 pm

I now have 7 of these P-64's and noticed that on 4 of them when I cock it I can see the firing pin stick out about 2/32" to 3/32" of an inch out. On the other 3 I can see only about half of that protrude. All of these literally look brand new never fired. Anyone have any input on their P-64.
Make sure you unload it before you cock to check.... not that you all don't know that but I would feel horrible if someone accidentaly checked and an accidental discharged happened. I did that when I was 24 with a shot gun dry firing to the ceiling.

Re: the shotgun accident- scary as well as embarrassing, isn't it. Many years ago I was proudly showing my wife my new Safari Arms Enforcer .45 and urged her to try the feel of the trigger. "Of couse it is unloaded, dear, just point it towards the kitchen window." 230 grain hardbal went through the glass and lodged in a small bank of dirt in the back yard. The wife went ballistic. You can imagine how I felt. Check and re-check! Better safe than sorry!

This is a guesstamate but maybe da manufacturin' process utilized a drill press manually operated. Tolerances could've varied..............

I was just wondering if because of there being less firing pin exposed to be struck by the hammer would there be a greater chance of a misfire.

That is strange. My new to me 71 sticks out more than the 73. Is it just a difference in the length of the firing pin?

My 72 firing pin (rounded hammer) sticks out further than my 75 (triangular hammer).

Good question. I think the OP should take both firing pins out and compare them.

Maybe there was a manufacturing change to the pins during the years.

I've never had a misfire with either.

I think that all the triangular hammer firing pin are shorter than the round hammer because the triangular hammer is heaver than the round hammer.The triangular hammer was suppose to an improvement over the round hammer why I don't know
I do know that on round hammer models the trigger return spring
had 4 coils on it with square wire and triangular hammer had 3 coils on it with thicker and round wire

Ah ha, that helps explain why the DA pull on the triangular hammer is a little heavier, I had wondered about that, I just thought it was because it was newer and hadn't been fire as much.

Thanks Norm

The triangular hammer increases leverage over the older round hammer. It's easier to cock. This change indicates the propensity of the personnel who were issued P-64s to cock and fire single action as opposed to double action. Feedback from the field, undoubtedly, perpetuated the re-design of the trigger. I have both designs and the triangular hammer is definitely easier to cock, but the round-hammered '67s are still my favorites, because I can cock either quickly, but the round design is more CCW friendly.

I have 7 P-64's and 4 have triangle hammer and 3 are round. All the round have the more protruding firing pin and one of the triangle hammer one's also has the more protruding firing pin. I am just beginning to wonder if it is not a production change at some point. It is interesting to say the least but I can't help but feel more comfortable with the (4) that have the more protruding firing pin.
