They look great. Easy to install (with the right tools.) Bright and very visible. Highly recommend. They will not disappoint. Fit my glock 19 perfectly. 5 stars.

I live in a very wooded neighborhood and take frequent walks after dark - both alone and with my girl. Because of this, I needed a decent pair of night-sights for my Glock 21. Not to sound too cliche, but, these did not disappoint. For aesthetic purposes, I got the green rear/front sights, and they look amazing. Now, in case you were wondering (because I know I was), the sights glow as a result of radioactive Tritium (in gaseous form) contained within the 3 small vials that make up the front and rear sights. This is the same substance used in many glow-in-the-dark watches, as well as various illuminated signs and paints. With this being the case, the sights are always glowing - whether it's day or night - and will continue to do so for years. The half-life of Tritium is 14 years; meaning that 14 years after the manufacturing of your sights, they will only be half as bright as they were when they were made. However, after some research into the topic, I'm lead to understand (through a single, perhaps unreliable source) that you will notice at least SOME loss of illumination 5 or 6 years after installing the sights onto your gun. Again, I cannot determine the validity of this source, but either way, you will get many years of use out of these sights. Installing the sights was fairly difficult for me; mainly because I do not have any proper gun-tools, so I was pretty much limited to your basic toolbox accessories. The front sight was quite simple, but the rear sight took the greater part of an hour to install. However, this is most likely because the rear sight must be tapped (hard) into place, and I was naturally a bit irked about going at my Glock with a hammer. It also didn't help that I knew that the sights contained a radioactive element (one which - I did not know at the time - is basically harmless), so I "tapped" when I should have been "hammering". Bear in mind, though, that the sights are made of very strong steel and are very tough. After I realized this, it became much easier to pound the sight into place. The point being; don't be shy about getting the rear sight on. It can take a beating. The real issue comes from the patience it takes to center it on the weapon. All in all, they're very good sights. They illuminate very well in the dark, and they make the gun look better than it did with factory-sights, in my opinion. Highly recommended.

Awesome and very, very bright in dark settings. Easy sight picture to quire in daylight or bright light situations as well. I typically use Trij/Ameriglo but these are impressing me more and more with usage and for the $$ couldn't be beat. Battle-tested and Made in ISRAEL. These new versions just list the M - Meprolight logo on the side of the rear and front (no longer -- TRU DOT as in the past). A+ so far on these, they installed on my older Gen4 G23 easily.

These Meprolight's are very similar to the OEM Glock night sights- particulary the pair with the white dot around the front tritium vial. The Meprolight's glow brighter at night than my other night sights *Trijicon HD's and Glock OEM night sights). Other people's reviews already show some pretty good pictures that accurately potray how the look, so I'm not gonna bother going there. I've noticed that the front sight markings are not quite as fast to acquire as they are for Trijicon HD's and some of the Ameriglow sights. Allegedly, Glock actually uses Meprolight tritium vials in their OEM night sights, but don't quote me on that. The Point of Aim is the same as the Point of Impact with the Meprolights, just as it is with all the other worthwile name brand sights; you don't have to worry about these shooting high or low. All in all, I'd say that these function just as well as $100+ night sights at nearly half the cost. Of course, it all boils down to personal style preference and what you look for out of your night sights.

I initially received the wrong color combo on these, but amazon made it right. As far as the install, it was about as easy as it gets. I use the VISM sight pusher and had no issues at all. I WD-40 the dovetail and it slid in like it's supposed to. For the sight itself, the pros are the definitely the brightness. They are brighter than Trijicons and Night Fision sights I have put on Glocks. Since this is a carry pistol, I am not looking for supreme target level accuracy. I more just want to be able to see my sights well enough to hit a man size target at night in a high stress situation, and these are great for that. I will say the front sight white circle in daylight seems a little funky (see pic). The circle just looks like it wasn't colored in sharply, some of the white bleeding out in certain parts. It's a little distracting, so it knocked off one star for me.

Mepro Lights used to be the standard night sights on Glocks when ordered with such and for good reason. I have a 20+ year old set of Mepro Lights that I thought to be perfectly fine in dim conditions. Then I got new ones for a new *ahem* toy, I bought. Woah! That's bright! People have and will argue about Trijicon, Mepro, TruGlo...I knew Mepro and they're the best for your money while still keeping a low profile...unlike Trijicon that wants double the amount of money and TruGlo that makes your sight look like it belongs on stage for Men in Black with how goofy and alien it looks. K.I.S.S= Keep it simple, stupid!

Great night sights for Glock. Mepro light makes the Glock factory night sights and I have had them on previous guns. Knowing this and with a good experience on my last Glock (with "factory" night sights), I decided the Mepros were what I wanted on my new Gen4 Glock 23. They Mepro's offer a larger tube and white ring than competing brands, making them easier to see and use day or night. The tritium has a larger white area to highlight in low and no-light environments as well. They are well built and as tough as the Trijicon's on my department issued G22. I have ran the Mepros through one-handed reload drills, using them to rack the gun on my duty belt and boots (simulating having a disabled hand). They are rock solid and had no problems at all. The only reason I would not recommend them is if you want to waste money on a more popular brand. If wasting money and getting less for your dollar is what you enjoy, then you should not buy these. But if you want quality at a price the other brands can't match, then these are the night sights for you.

Great sights for the money. I put Meprolights on my G19, and my son put Trijicons on his. I've used both weapons, and I prefer the Meprolights (for about half the cost). For me they present better in daylight, low light, and darkness. They are definitely brighter than the Trijicons, and are clearly visible when I open my nightstand drawer at night. I installed them myself with an inexpensive sight pusher tool - no problems. Mine are green/green, and being red/green colorblind does not appear to have hampered visibility, but I did stay away from orange for that reason. I actually like the front sight size, although some complain it is too large. For me it makes it easier to sight in faster, and I feel like I am more accurate than with the stock sights, although that could just be from having more experience now. I wouldn't hesitate to put these on my next weapon.

Very bright and easy to install I own several Meprolight products and they are top quality. I ordered the Green and Yellow combination which is very easy to see. Sights came fast and exactly as described love Amazon.ca

It really glows in the dark! The sights are built very well (supe tough). I recommend it

Great!!!!

Excellent sight - fits Glock 17 perfectly. These sights are very visible.

Very impressed with these sights. I found them even brighter than my Sig night sights. I'll buy them again if required
