jeremy kemlo Posted June 23, 2017 Share Posted June 23, 2017 I just changed my front and rear sights to warren tactical. The rear sight can be moved side to side with my fingers. I can tighten the set screw and it seems to hold well but makes me uneasy. Is the sight going to stay put with a set screw and a little loctite?

mpom Posted June 26, 2017 Share Posted June 26, 2017 (edited) Its probably going to be fine with the set screw tight, but for insurance, if you want an interference fit, you can raise a few burrs on the bottom of the sight by hitting it with a center punch at a couple of locations, say one on each side of the set screw. This will displace metal so that hopefully the sight will have some resistance to moving in the slide. Mark Edited June 26, 2017 by mpom Link to comment Share on other sites More sharing options...
ClintMorris Posted June 30, 2017 Share Posted June 30, 2017 You could also try red loctite under the sight/dovetail. Once cured it should help to keep it in place also gives with the set screw itself. Link to comment Share on other sites More sharing options...
MemphisMechanic Posted July 2, 2017 Share Posted July 2, 2017 @mpom was giving good advice. Peen / dimple the sight until it's a tight fit then liberally apply loctite to the sight, dovetail, and setscrew. Link to comment Share on other sites More sharing options...
Magsz Posted July 18, 2017 Share Posted July 18, 2017 Just make sure you dont get any loctite into the firing pin block recess... Link to comment Share on other sites More sharing options...
WarrenZ Posted August 13, 2017 Share Posted August 13, 2017 I had a defective Dawson (milled to small) front sight that I could slide through the slide slot by hand no set screw on the front so I staked it in place by slightly closing the dovetail with a punch not perfect but it worked.

Stake the sight not the dovetail...the sight is a much cheaper part than the slide. Link to comment Share on other sites More sharing options...
pskys2 Posted August 21, 2017 Share Posted August 21, 2017 Why in the world did S&W design the 2.0 to require the rear sight be removed to take out the safety plunger? Link to comment Share on other sites More sharing options...
mjkten Posted August 22, 2017 Share Posted August 22, 2017 Probably to keep tinkerers out. Link to comment Share on other sites More sharing options...

Yep, they've been like that since the beginning. But I've always put an Apex USB in mine when I first swap the sights, so it's not that big a deal to me. I generally stick with the sights I put on there, so it's a one time thing. Link to comment Share on other sites More sharing options...
