Shep Posted December 1, 2019 Share Posted December 1, 2019 Well for the second time in less than 10k my front sight decided it would rather be a solo act and abandoned the gun mid range session. This one had a small bit of blue loctite that obviously didn't work. I'm using Dawson precision sights. Would anyone happen to have a procedure they use to keep the front sight attached they're willing to share. Link to comment Share on other sites More sharing options...
BJB Posted December 1, 2019 Share Posted December 1, 2019 Mine used to loosen up too but luckily each time I saw it backing out before it backed all the way out & came off. I cleaned the set screw & the hole really well with contact cleaner removing all traces of oil, generously applied blue Loctite, let it cure a day, and thus far it hasn't moved at all. Is your Dawson loose in the dovetail? I had to use aluminum foil as a shim to make it fit snug. Link to comment Share on other sites More sharing options...
Shep Posted December 1, 2019 Author Share Posted December 1, 2019 It wasn't overly loose, could easily slide in by hand. Link to comment Share on other sites More sharing options...

Polymer Posted December 1, 2019 Share Posted December 1, 2019 I took a little piece of metal from used primers, cut and flattened it out into a circle that would fit into hole under the front sight so the tiny screw would have something to dig and hold onto better. Otherwise, the screw was going through my slide getting close to the barrel. I use red loctite for under the sight and a little on tip of screw. Before all this, the front sight would wiggle forward and backward after a couple sessions. Link to comment Share on other sites More sharing options...
Agent #1911 Posted December 1, 2019 Share Posted December 1, 2019 Loctite 620 (high temp) on the sight cut (do not use on set screw). Loctite 262 on set screw. Link to comment Share on other sites More sharing options...
Shep Posted December 1, 2019 Author Share Posted December 1, 2019 Thanks for the link polymer. I ended up putting 620 in the channel after lightly peen and a small ball of steel puddy under the screw that got a liberal coating of red loctite. Hopefully my spare site will just collect dust for a while. Link to comment Share on other sites More sharing options...
SloppyHayabusa Posted December 1, 2019 Share Posted December 1, 2019 I've just bitten the bullet and went with an Xtreme front sight over my Dawson sight that i've launched. I've heard the Dawson is a bit nicer than the Xtreme but the Xtreme has that fat set screw that along with loctite will give much less of a headache.

mrd Posted December 3, 2019 Share Posted December 3, 2019 (edited) My screw is long gone. I glue the sight in place with epoxy. Need to heat the sight to remove it, but it doesn't come loose unless I want it to. Edited December 3, 2019 by mrd Link to comment Share on other sites More sharing options...

Run a sight with a much better retention system. Link to comment Share on other sites More sharing options...

Before all this, the front sight would wiggle forward and backward after a couple sessions. I had to do the same thing on my Limited, as the hole in the dovetail was MUCH larger than the tiny Dawson set screw. I flattened a small piece of shotshell shot, matched it to the size of the hole, and pressed it into place. Then the Dawson set screw had something to bite into. In the dovetail I applied Loctite 609 retaining compound, which is meant to glue sleeves and bearings in place. It holds far better than blue Loctite.

IHAVEGAS Posted December 23, 2019 Share Posted December 23, 2019 When I was using the Dawson's I peened the bottom edge of the sights to create an interference fit. Xtreme are overpriced but I went to them anyway. Dawson on that gun is a square peg made to fit a round hole. Link to comment Share on other sites More sharing options...
Popeye212 Posted December 30, 2019 Share Posted December 30, 2019 I put the new sight on with the aluminum disc and and Loctite 620 it has stayed put so far. Decided to put a Burris Fastfire III on it even with the Fiber Optic the sights are still black night hunting with a Streamlight TL with a green filter. Sight paint has to be recharged. With the Crossfire and the Streamlight I should be good to go. Link to comment Share on other sites More sharing options...
pbgunrunner Posted January 2, 2020 Share Posted January 2, 2020 I've had good luck using an automatic counterpunch, pop a "divot" on both the right and the left on the center of the dovetail extension (the part that's held in place by the slides cut), front and rear. This pushes up enough metal to make an interference fit. You can also tap the top of the slide over the dovetail w a heavy non marring hammer to "close" the gap a bit. Shims and loctite always seem to work loose, especially softer materials. Link to comment Share on other sites More sharing options...

That didn't last too long since your last post LOL How many rounds do you think your Dawson sight lasted with that loctite 620, that's heat resistant so i think it's just a matter of retention Link to comment Share on other sites More sharing options...
Popeye212 Posted January 6, 2020 Share Posted January 6, 2020 It lasted about 30 rounds I think but didn't notice when it left. I was sighting in a Fastfire III I had mounted when it departed. I talked to a nice lady at Patriot Defense who does competitive shooting there. She lost one also in the middle of a round. She mentioned putting a bigger screw in the Dawson sight. I suggested to her that the problem would probably be solved by a tighter fit in the dovetail. Even if a little filing is required it will fix the problem with a snug fit. I will wait and see what comes on the market. Right now I am VERY pleased with the Fastfire and it showed two distinct advantages and what I was looking for. Accuracy at hunting distance and night hunting capabilities. Link to comment Share on other sites More sharing options...
