possible danger?

trent · Post by **trent** » June 2nd, 2007, 11:33 pm

I usually carry with one round in the chamber and the hammer down, but noticed recently that when sometimes when I drop the hammer it actually impacts the primer a bit, it leaves a tiny mark in the center.

This concernes me, I know I can just keep my finger on the hammer as I let it down, but has anyone else experienced this and is it a danger?

trent,

no I havent.

Im assuming your useing the safety to decock the hammer. The only thing I can think of that would allow this to happen is the firing pin return spring is worn out or broken. When the hammer is decocked the hammers energy is transfered throughout the pistol and translates into the forward movement of the firing pin.

I would take the firing pin spring out and replace it with one that Wolff supplies with the recoil springs packs.

I have never noticed this on my P-64, but have on many other semi-automatics. If you load the magazine, rack the slide and then fire off a shot, and then rack the slide again manually to eject the live round in the chamber, it will probably have a very small firing pin mark at or near the center of the primer. The Makarov is similar in design to the P-64, and it doesn't even have a firing pin spring, the f/p is free to slap back and forth in the f/p channel at will. Naturally, chambered rounds end up with little dings on the primer, but no harm is done. BTW, on my P-64 I can chamber a fresh round from a loaded magazine with the safety in the "on safe" position, allowing the hammer to follow the slide forward and never leaving the weapon cocked and in battery with a live round in the chamber. However, I do not know if this is the correct procedure for chambering a round or whether it will cause undue wear on some part, most likely the disconnecter.

I think Barnett is right about the firing pin spring or it might just be dirt in the firing pin
channel if you change out the recoil spring with one of WOLFF's springs they give you
a new firing spring with it , I don't think WOLFF sells the firing pin separate , if you need one
I got a whole desk draw full of them give me your address and I'll send you one no charge

I have also noticed that on 2 of my 4 P-64's. One other possibility I thought of was that on 2 of my P64's the firing pins stick out further than the other 2. The safety catch, when engaged stops the hammer mechanically however, on my other 2 P64's the firing pins protrude out more through the safety catch so they do encounter a very slight strike from the hammer but not the other 2 P-64's with shorter firing pins. I will try and take a photo of what I am talking about. I don't think however that there is anything to worry about cause I often practice shooting double action about 30 rounds at a time so I am constantly dropping the hammer with the safety lever mostly and then sometimes just with my finger so that I can practice double action shooting. Just my humble theory on the firing pin.... I do think the new firing pin spring (that comes with the wolfe recoil spring) is an excellent idea. I have them in all 4. I also now have Norms new trigger springs and slide stop spring.

Thanks Norm, recieved the spring yesterday and am now working on the p64 now, I'll post here when I'm finished. (this may take a while, I've never taken the gun apart this much)

all was going well until my safety detent #33 flew off somewhere

, I think it went into my computer, which I had not put the side plate back on yet, so on to another task

The case of the gun part in a computer...um...case.

what did your original spring look like?

BTW, the first time I took the slide apart my firing pin bounced around the room and found a nice resting spot underneath my couch. My post about it is somewhere in here.

alright, finished. when comparing the two springs there was a noticible difference in size, the origional spring was conciderably shorter, so I'm glad I changed it out it probably would have caused problems shortly down the road. (thanks again Norm)

Alas, it still taps the primer, it may be from the firing pin being long as stated above somewhere by . As a test I dropped the hammer 10 times on a single round (outside and not pointing at anything expensive of corse) and the primer never fired, so I'm reasonably sure that it will not accidently discharge, but I will always be mindfull when dropping the hammer to ease it down (just in case)

I welcome any other tips as well, the firing pin may be longer as stated by TTH but I see it as anything that should be replaced, Unless a professional opioion states otherwise (professional= knowing more than I do)

I think the round hammer gun had a longer firing pin the last time I checked because of the weight of the hammer I think, the triangler hammer has a shorter firing pin not by much but is shorter on the ones I have
