Just shot a hole in the shooting bench TT-33 Defective.

Just got my tt-33 from SOG. I cleaned and oiled it entirely.

The gun seems to function fine. Load mag, release slide, hold back on last round etc.

BUTTTTT.................


I put a round in the chamber WITH no mag and released the slide. I had the gun pointed down range and a little low. It went bang. I thought I must have touched the trigger or something. The round went forward, down range and It made a hole at the front edge of bench. Try again with it pointed at target and same effect.

They make dummy rounds to test function etc. ;)

You may have had a slam fire do to not having a mag in the weapon the same thing can happen with other semi autos like the garand when you try to shoot them singel shot.You need to lower the bolt onto the round not let it slam forward.

did you fidget with the safety?

It's a pre-WWII design. It's NOT made to be shot without a mag.

I checked the round that was fired and it was hit on the primer. So the firing pin must have hit it...

:confused: I owned one and have no idea what in TT design made the way you stated. Where did you get that info?

I've never owned a garand but I looked at parts diagram and did not see firing pin spring. TT has firing pin spring and if installed correctly there should be no slam fire issue.

I checked the round that was fired and it was hit on the primer. So the firing pin must have hit it...

So was the hammer down when you let go of the slide and handgun fired? Did you also check your firing pin, is it stuck in the fire mode and sticks out of the slide? If does not stick out, press on the firing pin from the rear with a punch, do you fill spring working and pushing back?

hey , somewhat unrelated but i just got mine from SOG as well and i am unable to tap firing pin retainer out to strip/clean that damn thing; how did you get yours out assuming it's polish?

I have a Romanian Tokarev and have had no probs. To remove the firing pin you have to punch the retaining pin out from left to right. I made a pin punch just for this by cutting down a drill bit and putting a "V" on the end to compress the retaining pin. I removed the safety as well... there is no doubt that this part makes this weapon difficult to operate.

this is a good web page to see the complete take down as well:

that looks pretty good. i am thinking about rounding&filing safety down so i don't have to worry about welding.

back to the retainer, the issue is it does not look like one of those v-like split ones, it is flat on both sides; but on the left there are 3 indentations almost like a mechanical damage of some sort. I am able to move it a bit in either direction with flat punch but that’s about it….i actually broke one of the smaller punches yesterday. Any ideas? I guess I can always boil the slide a few times to get the rest of the cosmo out...

Do you guys know any smiths in la area?

:confused: I owned one and have no idea what in TT design made the way you stated. Where did you get that info?

It's designed to feed ammo from the mag, not inserting a round into the chamber (by hand, no mag, as OP stated he did) and then slamming the slide home and forcing the extractor to then jump the rim of the casing while pressing against the chamber throat. That's just abusing the poor pistol.

Yes it will fire, if after chambering a round you drop the mag, but like many semi-auto firearms, it works best when a new round is fed from the magazine.

I think those have a history of breaking the firing pin with dry fire. I could maybe envision a broken pin doing what you said. That would be my first guess. I'm not a gunsmith, it's just a guess. You could search for dry fire and tokarev and see what I'm talking about. They sell new firing pins made of better steel that don't break as easy online.
I might be getting mixed up with the cz52 in same caliber as I've been reading a lot on both lately.
I could imagine in that broken condition it might go full auto on you during firing, I wouldn't feel safe firing that one until you fix it. If you do experiment more with it before a gunsmith, PLEASE consider loading only one or at the most two rounds in it at a time incase it does go auto on you, so you don't get hurt or the other gun in the other lane.

I am working on it today. When I have the hammer back and drop the slide the hammer is going too. What gives?

Fate

Something's amiss in the trigger group. Do you know how to strip it down?

Disconnector could be worn or cracked or hammer could be worn or cracked. If the hammer has a worn sear cut, that could be a problem too. You're going to have to get it apart to see what's going on with the parts.

My guess sear and or disconnect....if you have "hammer follow". I had a similar problem with a colt gold cup. replaced the sear and no more hammer follow. how well have you cleaned this weapon.

The round went forward, down range and It made a hole at the front edge of bench. Try again with it pointed at target and same effect.

I'm going with Fate on this one.......they were meant to feed from the mag, not encounter a chambered round when the slide comes forward.

if you have an import safety it may have jammed the sear or disconnector

Burnout...

It looks to me as if your retaining pin has been peened in. that will make it hard to get out. the best way would be to press it out from left to right... it will not go right to left. you could punch it out but it will be kinder to the slide to press it out. then replace it with a split pin type.

The import added safety is from the devil. Maybe the gun itself is rejecting it ;) They are pretty well known to mess things up too. I'd take it out if it were my pistol. It's unneeded with the half cock which is BOMBPROOF.

To quote the inventor of the TT-33, when asked why he designed it without a safety he replied, "Eees not safe. Eees gun." :)

+1, those safeties are designed to make the gun more unsafe.

I'd rather have it loaded, grip panels out with a live grenade strapped to it than operate that deathtrap of a "safety"

Remember kids! It was liberals who designed the tokarev "safety." Despite the fact that they had no experience in arms, or any business in designing for them; Liberals were the ones that OKed the on-frame import safety.

I think the trigger or sear (?) is worn out. SOG said they will exchange for another but I am out shipping and the Transfer $75! fees.

Thats Not expectable! tell them to send a new parts! I doubt it's the trigger. See if the sear is in backwards I've here of this on chicoms. or have them switch out the hammer group.

I've been scratching my head at this question. what would cause a slamfire?

To date, the only things I can think of is dirt, or the import safety, which I have since removed.

maybe my T54 is different somehow...
