I got my first SBH in 1974. Shot it a lot and all the screws were coming loose, grip frame and ejector.
I finally cleaned the screws with acetone and gave a dose of blue locktite to all the screws.
The grip frame has held up good and I had to retreat the ejector screw one more time after cleaning with the acetone.
You have to acetone the threaded holes as well as the screws to get any oil residue out of them.
