I had the opposite problem. When CGW milled my P-10C slide for a red dot, they installed a tall front sight, I am sure with a tiny amount of loctite. The tall sight cleared my Kydex holster...kinda. I love shooting the P-10C so I usually strap it on when I go to the range and shoot 10-20 rounds from a draw, just for practice.
Three weeks ago, I noticed my front sight was gone. I had finally beat it out by hanging it on the Kydex every time I pulled it from the holster over the last year. I got a new sight from CGW and will install it with lots of loctite AND modify the holster for the tall sight so I don't snag it again.
A better option for me will be to put a Holosun 507C sight with auto on-off on the P-10C like I have on the P-10F. That works great, and less need for a co-witness front sight. Not sure about battery life yet, however. The Burris sights eat batteries if you leave them on and there is no option for auto on-off. That works fine for a match gun, but not for a home defense pistol.
