What? You cut your finger? The firing pin retainer should be punched out from the opposite side by a brass or even better steel puncher of the same diameter (or a bit smaller). This is really an easy job. It should come out without much force. Is it rusted or what? If so try WD40 or some other rust remover. Personally, I've been using Ballistol oil on all my guns, including the SKS's for years. It dissolves rust very efficiently. I've never ever had any problems with removing any small pins or other parts. A visit to a gunsmith will cost you quite nicely for a job you could easily do by yourself. It's probably much cheaper to buy a set of punchers (or even one) than going to a gunsmith.
Ya I'm familiar with the removal process, it just wouldn't budge. I just sprayed it and tried again with the sks punch from toolkit and got it out fairly easy, should have done that in the first place lol. Anyways I swapped firing pins like suggested and the new pin definitely sticks out farther than the old one, so here's hoping that fixes it, gonna try to shoot it today or tomorrow and than I'll know for sure. If it is fixed than I just have one Chinese sks with a bunk firing pin I guess...
