I’ll have to post a pic of my 625-3 where the barrel has been tightening itself with shooting . The front sight now is canted a good 1/8” or more to the left . Unshootable now .
You can unscrew it, put blue Loctite on the threads and screw it back in with the sight vertical. Next day you can shoot it all you want and it will stay there. Clean the male and female threads with solvent, let that evaporate or blow it off, coat both threads, screw together, then wipe off any excess. Takes about 10 minutes to do.
