Loose Glock front sight post notch?

[Giggles]

Has anybody had their aftermarket front sights not fit like a glove into the notch? I have tried Glock factory sights to replace the plastic screw on sights and the HSP Th1rte3n sights and have had the same slight looseness.

The ones I've installed (trijicon, ameriglo, heinie, warren tactical etc) typically have a little play and can rotate. So, I always make sure that they're rotated so that they're aligned to the slide, and installed with loctite to fill the gap. I believe that's pretty normal.

I echo what Military said, when I install aftemarket sights, put a good layer of blue loctite around the base, then on the screw that secures it. After tightening and alignment I wipe off excess.

I do this, but with red Loctite. I also attempt to tighten the screw enough that I have to use an adjustable, locking wrench to ensure the front sight is plumb and square.

I don't recall which Glock night sight I installed first, but the manufacturer recommended red Loctite 262

and I am still on the same bottle 20 years later. Never an issue removing screws.

At that time, I don't recall any of the front sights I installed (PT, Heinie, Trijicon) being loose at all. Fast forward a few years and Trijicon, Heinie, and Ameriglo have all had quite a bit of play. Upside is the newer rear sights have been able to be pushed in without having to file the bottom of the dovetail which was the case with my older sights.

Thanks everybody for the help. I really wish that Glock would use a dovetail setup for the front sight. Plus I'm sure that it would allow for a more robust front sight that doesn't use a tiny screw. Maybe they'll put a dove tail front sight on gen 6.

Loctite it and you wont have a problem.

Loctite Paste Blue (https://www.amazon.com/Loctite-37643-Medium-Strength-Threadlocker/dp/B0053ZNMDE/ref=sr_1_sc_1?ie=UTF8&qid=1520361782&sr=8-1-spell&keywords=lotite+paste) is your friend here.

I use it like mortar on the front post before it goes into the slide. I use it on the screw too. Use a q-tip to clean up what oozes out. I frequently have to pop off the front sight with pliers, after the screw has been removed, when using this method.

I was visiting a buddy last week and his G19 was holstered sitting on the counter, I asked how he was liking the Glock and he said good so far. I asked to see it and he dropped the clip and ejected the round and locked the slide open and handed it to me, I was looking it over the noticed....no front sight. I pointed this out and told him this could be a problem!

I am a Loctite freak....!

A dab of JB Weld.

Thread locker on the threads, tighten, straighten, tighten, straighten, stop.

No, no, no, no, no, no, no, no.

Red loctite is sufficient. I’ve done sight installs on nearly 100 Personally Owned Glocks at my Agency. Red Loctite works and you can get it out with a little heat if necessary.

So too with JB Weld.

I've put on probably 50 or 60 sets, same RED (271). Fills the gaps and keep's em on. Almost all of them have had enough play that I always check with a set of calipers and make sure that it's straight. I use a parallel bar on each side and measure, then I have a pair of smooth jaw bent needle nose that are covered in tape just to "tweak" if needed. I believe Dawson Precision is the one who recommends Loctite 262 for the fronts.

The main thing is make sure everything is clean and dry. Degrease with isopropyl alcohol several times and literally glue the blade to the slide. I worked in aerospace for almost 20yrs so I clean and bond everything the same way we did at Boeing.

I've had a recent Trijicon suppressor height front sight that came with a screw that was about .5 mm too long so the front sight could never be tightened sufficiently. I returned them for Meprolights which had a proper length screw.
