Feyachi NS16 Night Sights Glow in The Dark for Glock Pistol 17 17L 19 26 27 33 34 38 39, NO TRITIUM

I ordered these sights to upgrade the pre-existing ones to night sights for a home defence role in my arsenal.Firstly the pros- excellent construction, made from aluminum-glows bright and very distinguishable-easy install (done it a few times)-improved my accuracy (your results may very due to postal management and overall practice)Cons- I would like to see a set screw on the rear sight between the posts to eliminate any play. I have reached out to the company about this and they were very fast at responding to my inquiry by saying they will look into this suggestion.As I have stated, I've installed many sights and this pistol is not exception to that. By doing so it may worn away the sight groove and this issue may be present. I may have lucked out on my set and they stay put after over 200 rounds. This pistol was my everyday carry for over a year and a half till I decided to go for a smaller carry gun. So it has been worn and even in its current state the sights hold firm.Overall the sights are quality made and from a reputable company. I would recommend these to anyone currently looking to make a upgrade to a very vital part of any pistol.Thanks for reading from a firearm enthusiast!

I bought these sights to replace the 7 yr old, dimming Trijicon tritium night sights on my Glock. The bigger dots on the Feyachi sights also help with my aging eyes. I installed them today and am really pleased with the results! Here are a few points I can confirm / refute regarding some of the comments posted by other reviewers that I read when trying to decide whether to buy these sights for my Glock 26. I don't know if Feyachi has made design or manufacturing changes since previous posts were made, but as of May 2023 here's the what I found:1. The body of the sights are made of steel, not aluminum. Both front & rear sights jump to a magnet2. Installation - the rear sights were not a loose fit, they were pretty tight, but moved with a sight pusher. The new rear sight went on easier than the old Trijicon rear sight came off.The front sight appeared to have an oval-shaped post to match the oval-shaped hole in the slide, not a round one as another reviewer stated. When tightening the hex screw you do need to watch the front sight alignment since there is a little bit of slop in the post's fit, which allows it to misalign a tiny bit if you're not watching when tightening the hex screw.3. The sight dots are, as many noted, photoluminescence (not tritium). That said, when I hold my 400 lumen pocket flash lite to the sights for 3-4 seconds they glow incredibly bright, and are still glowing, tho dimmer but still functional for aiming in the dark, 15-20 minutes later.All in all a good value for the money. I'm going to buy another set of these sight for my other Glock too!

Are these as good of quality as trijicon? Absolutely not. But for the money, they are cheap sights that work. They slid right in with no issue at all. Fit is fine. There are casting marks on the sights, and the dots are gritty. But they are better than factory sights by a far margin. If you are looking for a Caddy for the price of an Aveo, this isn't it. But if you are looking for functional night sights that are easy to install and won't break the bank (especially if you got your Glock for 250 as police trade in), these do the job for cheap.

These sights have some good features, but also 3 egregiously bad ones. Therefore, I so not recommend these sights. But if you still want to buy them, then be aware of these issues and tips:#1 for sights that don't have a precision fit, these are too expensive. A $30 set of sights should fitproperly.#2 The fixed elevation of these seems to be radically different from my Ameriglo suppressor sights forGlock.#3 They are made of aluminum, not steel and are very easy to drill holes through (high quality steel hardsights are impossible to drill with conventional had drills and bits)#4 glue or epoxy the rear sight in the dovetail (details provided later)#5 replace the useless glow dots with more visible bright white Sally Hansen "Hard as Nails" nail polish#6 consider glueing or epoxying in the front sight post (details provided later)Another negative attribute shared with a lot of other sights is that NONE these light charging glow-in-the dark sights are useful, ESPECIALLY the stupid 1 glow-dot 1s that some Ruger pistols come with new. They aren't useful because I mean, what am I supposed to do at night with them, ask my assailant to wait until I charge up my sights with my flashlight so I can aim in the dark and shoot him? #2 Ruger 1-dot sight is useless if I can't line it up in the dark rear sights that I can't see at all in the dark.The good: the front sight thought not the same base tightens down and doesn't seem to move, nor give the impression that it might move if bumped because it's small and goes on rather tight with a Glock front sight tool.In the daytime, these dots are a lot better than most of the ones I've seen on more expensive sights. They are big and contrasty with the black sights and are easy to see and line up properly, easier than OEM and expensive after market ones, which I routinely paint white to make more visible, but these I don't have to.Summary: Not recommended because Neither the front nor the back sights fit properly. The rear sight is sloppy in the slide dovetail, can be pushed back off slide with a finger. The front sight doesn't have the proper oval base in the Glock front sight post profile to keep it from spinning, so it has to be tightened down all the way to keep it in place, which necessitates orienting it parallel with the slide BY EYE before the last turn! Then if mounted you have to worry about whether the fix elevation is zero to your Glock or not and unlike expansive sights like Trijicon, you cant send the front post back and get another height. Like I said, these are $5 sights posing as $30 ones. you're better off sticking to the Glock polymer ones directly from Glock .But I have a recommended solution for both that involves glue or epoxy. I put superglue on the base of the rear sight, before installing it which stiffened it up quite a bit about like an expensive sight fits. JB Weld would also be good. In both cases, once cured, the adhesives will hold and will not harm a Glock slide finish and can be broken loose again and removed with a sight pushing tool. Note that I did not glue or epoxy down the front sight post Because:Putting glue or epoxy on the front sight post requires more meticulous application because the adhesive, while not harming the finish, will grab rather well and there is no vise or other took available for the front sight to push it out of the slide. So if you want to use glue or epoxy on the front sight post, I recommend this procedure:scuff the bottom of the post and apply a small amount of the epoxy or glue put a light film of oil on the firearm slide at the front sight post mount and then mount the sight and tighten it almost all the way down. Then get an appropriate precision measuring tool (frankly I have no clue what measuring tool, but I am sure there is one for this and I know that I could make one myself if necessary) and measure each side of the sight at the dot to each slide of the slide to make sure they are equidistant and then completely tighten the base screw.Improvement on these would be to make the front dot bigger than the back dots for proper perspective and elimination of the useless glow dots in favor of even more contrasty white dots (which I do myself tih white fingernail polish)a bigger dot in front is needed so that that in shooting perspective, all the dots look to be the same size. Right now, the front dot is the same size, but it looks smaller when aiming because it is further way. It would be a LOT easier and quicker to line the dots up properly If in shooting position, tall the dots all appeared to be the same size.Having said that, None of the more expensive 3-dot sights make the dots different sizes to compensate for perspective.
