    OK, how screwed am I?

    I wanted to install night sights on my G19. I watched all the "how to" videos and read all the related websites. Seemed simple enough, after all I can change a tire on my car with no problem.

    So I ordered a set of Trijicons, a brass punch and some Loctite 271.

    Did the rear sight first, no problems. I've actually done it before many times on other handguns.

    Prior to removing the front sight I made sure my 3/16 socket matched the front sight nut and it fit perfectly. So I removed the front sight, it was on there pretty good but I twisted it off with a vice.

    I inserted the front blade sight, added a couple drops of loctite and EVENTUALLY got the threaded screw going into the front sight blade. Now I know why other countries use small children for this kind of work, trying to get that lined up with my adult fingers was a major pain.

    And then I started turning the nut with the 3/16 socket and everything was going fine until....my socket lost contact with the hex nut head. But it was still far from being securely tightened.

    I was able to get it an extra turn or two with some needlenose pliers but this clearly wasn't the correct tool for the job either. And nothing else in my toll box that can fit inside the slide will grab that flat hex screw and turn it the rest of the way.

    So it's still pretty loose and the loctite is setting up.

    Now what?

    I'm hoping there is a way to "un-loctite" this thing as I really don't want to have to purchase another front night sight (not even sure Trijicon sells them that way) in addition to likely paying to have a professional do it correctly.

    And if I am really screwed, who is the best to send it to for sight installation?

    Thanks.

    Uh, take it out before it sets?

    After it sets, warm it with a hair dryer and get a front sight tool for under $10 and a new screw, unless you stripped the front sight.

    I have never used any loctite or any other "glue" as there is really no need, and I have NEVER had a sight come loose, and I have installed quite alot. If you feel you need Loctite, use red loctite.

    You can also file the face of your socket flat so that it fits completely over the very thin head of the screw.

    If you use a normal socket or something of that type you are not going to be able to tighten it all the way. A normal socket's end is recessed and when the sight screw gets tight the socket won't get a grip.

    Take the sight off as soon as possible hopefully before the loctite sets.

    Are you sure you didn't use the longer screw from the glock front sight with the new trijicon sight and now it's bottomed out?

    Will a hair dryer really work on loctite 271? If so, what is the point of loctite at all? The barrel will get it way hotter than that.

    Positive. There was no screw on the Glock front sight.

    Yep, that is what I learned today.

    And I have nothing that will remove the screw, even the needlenose can't get a good grip and the loctite IS set.

    Looks like I need to get the tool tampashooters mentioned, until then my carry gun is out of action. This is why I hate those damn DIY videos and websites, NOT ONE OF THEM mentioned I would need a specific Glock front sight tool to do the job.

    Grrrr.

    A front sight tool made for the job will also save you employing the small children you speak about - it will hold the screw and allow you to insert it into the sight.

    People do some stupid stuff to "lock" on their front sights, which is totally not necessary... Once you get the tool, you may need to use some pliers with it, so you get some leverage to break the loctite.

    I've found that the bit holder of my Victorinox cyber tool fits the screw perfectly.

    Use a soldering iron to heat the head of the screw. This will soften/melt the Locktite and allow removal w/ the correct tool. These are steel sights, right?

    That's why you always "dry fit" all parts before going "wet." You find out what does/doesn't work in your chosen technique.

    I was once having a real bad day at the range with my G19 until I noticed the front sight was loose and moving around.

    I'm interested in how this can be avoided without using locktite or similar. Particularly when most sight instructions warn about over tightening.

    Heat up the screw from the inside of the slide with a blow dryer on high heat for a few minutes then use a proper front sight tool to unscrew it. The heat will soften up the loctite.

    If you need a front sight tool send me a PM.

    I did some reading into the various properties of Loctite and yes, it was common to see recommendations to use heat to soften the red Loctite before attempting to remove it.

    I recently replaced the front sights on five Glocks (26s and 19s) and using the proper tool that was provided with the sights (Amerglo), the first two Glocks I took to the range both had the front sights loosen up considerably at under 100 rounds. I mean like they were really quite lose. So I remounted them all with red Loctite and that was the end of those problems.

    Just my experiences for what it is worth.

    Hand tighten it and done, I don't believe you can overtighten by hand, and I've never had that problem with Night sights, or regular letal sights. Also, I have never ever had a problem with loose sights and I shoot alot, and many different Glocks, which all have aftermarket sights that I have installed without loctite. If you want to use loctite, go ahead, I was just sharing my experiences.

    I have seen a few lost on the range with people that use their guns in and out of the holster quite a bit and I have tightened quite a few that were loose. I have used lock tite on all and have changed many that were installed with red and blue lock tite. A little heat is your friend but be careful if the sights are fiber optic. Blue lock tite works under normal operating conditions but some are rough on equipment and need to use red lock tite.
