Cracked breach face repairable?

Are you sure that's a crack? It's not going from or to anything, and it doesn't look like it's relieved any stress. If the crack continued, what would come off first?

In my gun, I'd be sorely tempted to skive, weld, grind, and shoot. You gunsmith will likely not be so daring.

From the pictures I would have thought the lines are for part that was peened or dovetailed into the slide.

If the crack is below the casehead when it is in battery, then if/when it breaks off, pressure containment will not be affected. The case will be chambered to the proper depth and the case properly supported in the chamber.

I don't know the locking mechanism of your pistol, but this is not locking mechanism structure, so the breech will be locked when it should be locked

That flange is used in picking up a cartridge, and when it breaks off, you will have feed issues.

Is the flange file hard, or is it soft? A welder could tell you if welding that would remove any heat treat. If it is not heat treated, maybe a skilled welder could lay a bead, which could be ground flush, without removing any heat treat or hardness.

Personally, I think you should shoot that pistol till it stops feeding, and buy another, keeping the old one for parts.

Looks like a manufacturer defect.

If I'm in doubt I won't shoot it. If a gunsmith or someone associated tells you it's ok to shoot a gun with damage evident to any part, find a real gunsmith.

Just isn't worth it. A lot of folks like com bloc stuff, I find it all sketchy in perfect condition. The crack looks like nothing but I don't have it in front of me so I don't know. My opinion is that it should go for a visit to a different Smith for another opinion. When in doubt, err on the side of keeping your eyeballs and fingers in their original location and don't shoot it. Maybe over cautious but I'd rather be called that than wish I hadn't done something I knew could be a problem.

Just my 2 cents, worth what ya paid for it.

Its a blow back action. Nothing is locked closed to blow apart. Only thing I can think of is the bolt may bind. It looks like that is a part added to the bolt like a guide rib. Have you removed the bolt and looked at the under side? I doubt its a safety issue. Good luck.

That looks like a poorly fitted dovetailed insert, rather than a crack. Should be fine.

So this was chambered in 9mm Para. originally? I looked at some other 7.62 TT33 slides and and they dont have that little projection at the bottom. I suspect that Norinco machined that peice and inserted it into the slide to improve function with 9mm ammo. The gap is just rough dovetail machining, shouldn't cause any safety issues. I dont know if there will be any feeding issues from converting it back to 7.62x25, however.

Here is a Russian TT33 in 7.62. See how the bottom of the breechblock is smooth?

Right on, glad its not actually broken!

Welcome to forum, btw- cool avatar!

The Tokarev TT30/33 is a locked-breech recoil operated pistol. Locking is accomplished by lugs on the barrel seating into corresponding recesses in the top of the slide; much like the M1911-series pistols. The part shown in the photos is the slide: the Tokarev does not have a separate bolt, as such.

In the original photo, that has got to be thee MOST fugliest attempt at machining I've seen in at least 45 years. That cutting tool must have been dropped on its radius and onto a cement floor, at least five times. Poor job to say the least!

Thanks. Didn;t know that. I thought they were a copy of a old Browning blow back design.

This is what the bottom of my slide looks like, Norinco Type 54 in 7.62 Tok.

Poorly fitted joint.
Need more pics of the outside of the bolt to try and determine what part they mated to the bold body.
