Just wondering if anyone else has experienced this problem. I purchased a 625 JM about two months ago and to say I'm pleased with it is a huge understatement. I have about 600 rounds through it now and after the last 2 range sessions I found several screws backed out almost to the point of falling out. One was on the thumbpiece and the other was the rear sight leaf. Is this fairly common? Thoughts on using locktite?
