Truglow front sight issue G17 Gen3 (P80 Classic)

I’m a TFX user too!

Pretty much follow the exact same installation procedure as you do, but once the front sight screw is tightened down, including a drop of red Loctite, I use a small precision crescent wrench to move the front sight just a tad clockwise or counter clockwise as needed.

I do use a stainless machinist ruler to do the alignment.

 

I’ve installed 8 sets of TFX sights on my Glocks in the last year, no broken vials yet!

EDIT: Loosen the front sight screw and make sure you can line things up that way. If not, something might not be right.

 

For whatever reason I'm OCD about front sight being straight and the best way I've found is don't fully tighten up the screw just get it tight enough but still able to slightly move the sight then eyeball the sight and get it where you want it and then finish the tightening. Remember you don't need to crank down on the sight it just needs to be snug, if after that your not satisfied then loosen the screw just a little and try to center again and repeat until your satisfied.

Using blue loctite either 242 or 243 you have plenty of time before it dries. I've installed dozens of front sights and I've found I can tighten down the screw and then loosen it back up if necessary for 20 minutes plus without messing up the glue properties.

I know how it is after you put the loctite on the screw you feel the time ticking but remember blue loctite takes a long time to dry so you can tighten and loosen the screw several times without any negative effect to your glue hardness.

Just remember to apply pressure down on the screw head when loosening and tightening you don't want to strip the screw head, as long as you do that you can mess around with it and get that front sight just how you want it. It is certainly better to do it this way instead of deciding the day after installation you don't like the position of the front sight.

If you do wait until the next day it's not a huge deal as long as you did not over tighten the screw you just need to take the sight back off and using alcohol, qtips and a brush remove all the dried up loctite and then clean the surface with the alcohol and start over.

 

I use the Dawson Precision steel front sight tool

I have 2 of them, one that gets all the use with worn edges. The other is for emergencies when things go south and I need the tightest fit.

 

I have yet to install a front sight on a Glock that didn’t have some play in it where I had to wiggle a little here and there during the tightening of the screw until I had it perfect...sometimes this took more attempts than others...including the truglo tfo...

DO NOT USE RED LOCTITE

 

The front sight screws are so short and small I’ve never had an issue removing the sight with the steel Dawson Prevision tool that I used a drop of Loctite Red on.

On the other hand I’ve seen 2 front sights come off of Glocks during a match that only had Loctite Blue.

 

There is another thread about this very same issue if I am remembering correctly. It turned out the piece of the sight that goes into the slide was machined wrong and was crooked. I think he returned the sight. I even think that thread was the same sights as this thread. If it won’t straighten out, then I’m betting the sight is not machined correct.

Edit- I found the other thread discussing this.

Flip over the front sight and see if you can tell if it looks like it’s machined wrong. I find it weird that there are now two if not more threads about this particular sight being crooked. I wish you the best in getting it figured out as I know these things can be frustrating.

 

Are you sure they’re not counterfeit? Amazon sells tons of fake name brand accessories.

 

I got burned by some fake earmuffs (not a fun surprise on the range) and a friend got burned with some fake trijicons. Packaging looked legit. Not saying yours were fake too, but something to keep in mind.

 

Were they sold by amazon or a third party?

The 8 sets that I’ve purchased were all sold by amazon
