Sorry Jeff, its not coming off. I picked up the gun from FEDEX distribution center because it was the second SNAFU. If I waited for delivery, it would have been 2 more days. The gun was a complete rebuild. Accu rails, Kart NM barrel gunsmith fit, trigger job and new ejector.
I went directly from fedup to the range. I had lots of ammo, but had to buy a magazine because I forgot them. I shot a few to dial it in, then did some accuracy testing. At about 50 rounds, I could no longer hit a target at 25 yards, so I checked the sight. It was loose. I took it to the "gunsmith" at the range and he tightened it up. I don't know how or how much. After another 30 rounds or so, it came loose again. I went home.
I removed the sight. It looked like where the holes were drilled and tapped were up a little compared to the rest of the flat. I took a large fine diamond stone and trued the flat on the slide. Out came the RED Locktite. I trued the bottom of the sight with the stone. I cleaned everytghing with an alcohol based solvent and applied the locktite to the bed and screws. I torqued the screws to 21 inch pounds and let it sit for 24 hours. I have shot about 300 rounds since. Its still there and not moving.
