No, not above the neck!
On my Ruger Super Blackhawk in .44 mag.
After every shooting session, I'm finding the screws loose on my stainless SBH loose at least a quarter turn. I've tried (blue) thread locker and they are tight before shooting. My handloads are fairly mild compared to factory ammo (around 1000fps), as is recoil. This last shooting session, the pin that holds the rear sight on backed out over 1/4 inch and went back in with finger pressure. I emailed the factory and got very little response other than "use LocTite". Duh.
Is there a special requirement like LocTite primer needed for stainless? I've never seen any other guns do this. Last year, while shooting around 100 rounds, the ejector housing screw came completely out and parts flew everywhere. Fortunately it was an indoor range and I found all the pieces. Sure makes me nervous, though.
