Once again I would like to point out that your barrel is pressed in, not screwed in, not pinned in, not welded in, but PRESSED. Exactly how long do you think it will stay tight? There was once a company that made a 22 revolver with a pressed in barrel. I believe it was FIE. You don't see them anymore. Any idea why? I will give you a hint, THE BARRELS SHOT LOOSE ON THEM AND FELL OFF.
