So I bought this Norinco tokarev with a 7.62x25 barrel and parts to swap it, about a week into having it and only shooting it 2 times I noticed a small crack below the firing pin orifice and it’s been at the gunsmith for a week. And it doesn’t look like it can be fixed but a worker said it looks like it will be fine, but I can’t imagine that being fine in anyway. After sometime it will expand and possibly blow apart right ?? I’m not sure if I’m overthinking it but it just doesn’t seem fixable. Unless they get a new slide. Any advice would be greatly appreciated!
