Last Fall I got 3 new barrels factory fit to the same frame. This Spring, I put them all on their own frames. The .357 locked up tight and proved to be a tack driver, but I noticed a slight rattle in it like something was loose. It locked up tight on a .002 feeler. You couldn't pull it out. I found it was rocking on the pivot pin, so I sat back, had a beer, cut the can and shimmed the pivot. End of rattle. Now, I've got to slam it pretty hard to lock up, and sitll can't pull the feeler out. Now, do I leave it or touch a file to the latch shelf?
It is right on. Nailed a starling dead center at 110 yards yesterday. It's a scout mount pistol scope.
