pbcaster45 Posted June 29, 2015 Share Posted June 29, 2015 The rear sight on my 40 STI Edge keeps coming loose, I've tried Blue Loctite on the setscrews but it didn't hold. I'm not sure if it's the rear sight or the slide cut but the fit is a little sloppy. I can slide the sight from one side and out the other with finger pressure alone (with the setscrews loose). I don't want to try a stronger Loctite; does anyone know if anyone makes an oversized/gunsmith fit version for the LPA cut? There is very little contact between the slight and the base of the sight - I'm stumped! Link to comment Share on other sites More sharing options...
rishii Posted June 29, 2015 Share Posted June 29, 2015 I had a smilar issue with a lpa cut sight What I did was remove the rear sight And drilled a shallow detent where the set screws contact the bottom of the sight cut in the slide Reinstalled the rear sight an used loctite 271 on the set screws If you can see if you can get new set screws, because the one you have may have been buggered up by constantly trying to Tighten up Link to comment Share on other sites More sharing options...
mike l m Posted June 29, 2015 Share Posted June 29, 2015 Why not try a soda can. Cut a piece of can the size you need and slide into place. It should take up the slack in the dovetail. Thanks, Mike Link to comment Share on other sites More sharing options...
racknrider Posted June 29, 2015 Share Posted June 29, 2015 You could peen the sight or the dovetail Link to comment Share on other sites More sharing options...
pbcaster45 Posted June 29, 2015 Author Share Posted June 29, 2015 That piece of aluminum idea sounds interesting! I think I'll give that a try. I don't want to do anything permanent just in case the STI Warranty Department finally gets in touch. It's been a month so far, they must be really busy!

pbcaster45 Posted June 30, 2015 Author Share Posted June 30, 2015 I was looking at the Kensight webpage and noticed in the installation instructions that they recommend blue loctite IN the dovetail. Anybody with this problem tried that? Link to comment Share on other sites More sharing options...
lppd4 Posted June 30, 2015 Share Posted June 30, 2015 I thought the windage screw hole was drilled and tapped into the slide, Unless its broke you would not be able to move the sight because the windage screw would hold it in place Link to comment Share on other sites More sharing options...
pbcaster45 Posted June 30, 2015 Author Share Posted June 30, 2015 That's true on rear sights with the Bomar sight cut. My STI has the LPA sight cut which is different. I'm not sure when STI made the change but most of the Edge pistols I've seen on the forum seem to have the Bomar style. Link to comment Share on other sites More sharing options...
Toolguy Posted June 30, 2015 Share Posted June 30, 2015 The elevation screw is what is drilled and tapped into the slide, not windage. It can still have some side to side movement even with that setup. Blue Loctite in the dovetail and setscrew would probably fix it. Link to comment Share on other sites More sharing options...

gng4life Posted July 2, 2015 Share Posted July 2, 2015 I have used Red in many of dovetails. I used to have a front fiber sight that kept coming loose and I put Red all over it, no problems after that. Link to comment Share on other sites More sharing options...
pbcaster45 Posted July 2, 2015 Author Share Posted July 2, 2015 I decided to use Red Loctite on the dovetail and Blue again on the setscrews. Using the factory rear sight, I'll keep the Kensight in reserve! Will report back on results. Link to comment Share on other sites More sharing options...

pbcaster45 Posted July 8, 2015 Author Share Posted July 8, 2015 Hey! I don't want to give the impression that STI didn't get in touch - they did, but I'd already taken care of it! Link to comment Share on other sites More sharing options...
