I guess that I need to get every one of my guns attended to since they all come down solid on the flats and the bolt holds them there. And what possible reason could there be to allowing flex in the lock up?
And just to be clearer, on face/off face is the Result of properly fitting the hinge pin/hook and the flats.
I'm fairly certain that Lucio Sosta, a Beretta factory and later Perazzi factory trained gunmaker, knows how to fit barrels and locking bars. And that's how he does it.
Good enough for me.
