Hello all, I just got a VP9 on a trade and took it to the range this afternoon. For some reason, the trigger block bolt is working its way out of the frame during shooting. It backs out about 1/8" after a few rounds and I get a failure to fire once this happens. Just a dead trigger until I push the pin back in. Searching didn't help, and I'm unfamiliar with this weapon. Please help.
