Meprolight Tru-Dot Night Sights Set Compatible With Glock 19 17 20-25 26 27 28-35 37 39 43 43x 42 48 - Self Luminous Fixed Tritium Sights, Green, Orange or Yellow Available on Rear Sight

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.

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.

These sights are everything they advertise. Day and night, nice glow at night not to bright not to dim just right. The gunsmith had no problem installing these.

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.

Would like it better if you could specify what height you are ordering. Glock sights come in like 5 different heights. You can tell by the different length line diagram raised on the side of the sight. I think these are the level above "zero", at least the last set was that I just put on my model 36. No big deal, just changes your point of aim slightly, but it is something to be aware of. By the way, do yourself a favor and buy one of the sight adjustment tools on amazon. I cringe reading reviews about using drift punches and sand paper. Do it right. It really is worth it. Only takes about 3 minutes when you have the right tools, and makes it easy to fine tune at the range if you are off on your initial placement. I had these on my duty weapon (Glock 21) when I was a cop. They work great, and I actually shot better with them than the stock "Ball in the basket" sights. For some reason, my brain centers that front dot better in a three dot configuration. I also like the option of the orange rear sights. Helps you focus on the front sight where you should be for close up combat shooting in low light, which is what you're buying these for anyway. Just my 2 cents... :)

What a difference it made on my G17 just amazing. The fitting on the rear sight was slightly to big tried multiple times hitting it with the nylon punch and it just wouldn’t budge. I took the sights back out then filed down the dove tail just a little bit and after that it fit just fine with a couple of good hits with the punch. Overall an amazing product!!

Even though I waited an extended period of time I understand it's the pandemic to blame but the product itself is very good.

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

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

Good
