Tokarev question

[jcuffe6240]

Just took my new Tok to the range today and fired off 50 rounds of S&B 85 grs FMJ. I noticed that the primers on the spent casings were having a weird deformation and wondered if anyone knew about this or if I should be worried. It seems that the firing pin is hitting and then sliding a bit.

Comments?

"firing pin is hitting and then sliding a bit" Explain... the image is hard to interpret.

Here is a close-up of one of the primers.

That does look kind of odd. What make is the pistol, and has it been thoughly cleaned?

 

[jcuffe6240]

It is a 1953 Russian Izhevsk TT33. I have field stripped it, but not removed the firing pin. Would that help?

YES... Looks like firing pin Spring is not working Right. Firing pin stays out when extraction-ejection begins, making mark on primer by dragging, Cleaning and/or replace firing spring,and check if firing pin is straight

Does anyone know what the min/max length is suppose to be for the firing pin spring? I measured mine and it is somewhere between 1.60 and 1.62 inches.

Mine does the same thing. Has for about 600rds so far, never had a problem. I have a 1942 Izhevsk

 

[jcuffe6240]

Thanks ArtyMan. Have you ever disassembled the firing pin and spring and measured your spring? Do you reload the brass? Any issues when doing that?

I've seen this on TT-33s and CZ-52s. Was it spitting brass pretty far? I see some of the case mouths are dinged. Looks to me like your recoil spring is a bit used up, get a new one. Should fix the primer dragging issue. I hear it's usually caused by the old recoil spring not keeping the action closed just long enough. As it opens, it drags across the firing pin. Seen it happen with 1911s that are loaded too hot or have a weak recoil spring.

Generally not an issue, but it can sometimes break your firing pin.

some guns just do that. My Steyr M9A1 did it...

Ive never disassembled the firing pin, Im not sure I even know how to be honest Right now Im just using surplus, my TT-33 destroys brass so Im not sure its worth reloading, I may just hunt for a 9mm bbl when the surplus dries up.

 

[jcuffe6240]

Meph, it was tossing the brass nearly ten feet after hitting the roof of the range. I am hoping to still reuse the brass to reload.

 

[ArtyMan]

I found my brass.... about 7 lanes over to the right! Ive never seen anything kick brass as far as my TT firing surplus. Ive had quite a few cases eject in about 5 pieces too, never stopped the pistol from firing. I did unload and check for safeties sake, but the pistol ejected the junk and locked into battery with a fresh round, worked perfectly.

With the hammer down, does the tip of the firing pin protrude from the f/p hole? Had an aftermarket f/p with this condition that caused similar results. Shortened it and cured problem.
