Trying to change out a Beretta 390 recoil spring.
I am replacing the recoil spring but can not get the recoil spring cap off of the stock bolt tube. The cap has a flat on it and am concerned about a wrench slipping off the flat and messing up the threads.
Is this the best way to put the new spring in?
I also noticed that the stock tube has holes in it near the receiver. I can push the recoil spring guide far enough in to get a punch through the holes. Can this be unscrewed?? Is it lock-tited in? It seems if it unscrewed, this would be an easier way to put the new spring in, because you could retain everthing with a punch while screwing it back in.
Any adviced would be appreciated.
