It usually happens when you swap out your pistol grip, here’s the deal. Same thing happened to me and it was driving me crazy tried all bunch of stuff. I finally realized that , let’s say you replace it with a Magpul grip. If you look closely the Magpul grip it a bit thicker than your factory grip so when you screw in the screw the screw doesn’t go all the way in. So what I did was I put in the screw without the lock washer and it fit perfectly. It’s in there right and have not had any problems with it. Or just get a screw that’s a bit longer and you can put the lock washer on. Fixed
