AMERIGLO Protector Front/Rear U-Notch Green Tritium Night Sight Set Compatible with Glock Gen 1-4 9mm/.40/.380, Gen 5 10mm/.45 (Including MOS Series)

I installed these on a Gen2 G19. Darn near perfect. POI was under the dot at 7 yards and top of the post at 25. Super visible. Rear notch is wide but not too wide. The orange dot really jumps out! I had a green set of the CAP sights on a G43 and even though I typically prefer green to orange, with these sights and my eyes it is the opposite. The U notch is great because it lets you see the whole front sight and really lets you dial in decent sight picture quickly. I was able to install these without using a rear sight tool by placing the slide in a padded vise and using a steel punch with an empty .22 case over the end of it to prevent marring. It took about 15 minutes of running the bottom of the sight over a file, testing, and then filing some more (these sights are hard) but it eventually went in and lined up correctly with no problem. The finish on these things is pretty tough, too. Despite my repeatedly banging away at the rear with the punch there are no permanent visible marks (ymmv). I also really like how low these are to the slide compared to the Heinies I've used on G19's before. They are much less likely to rub on the inside of a holster. Also, despite the serrations these don't irritate my skin when carrying AIWB. I have absolutely zero buyer's remorse and can't imagine being any happier if I had spent twice as much on another brand. Edit: I have added a picture. It was taken at (my short) arms length and then zoomed in to show the relative size of the dot in the notch. It is precise enough that you can easily tell that the sights are slightly misaligned in this pic.

I have mainly ameriglo night sights on all my glocks and other pistols. I am a fan of the Bold option but I got a steal on a brand new G26 G3 a few weeks ago and it obviously came with the stock glock sights, but I am a fan on the rear U-notch sight! I can do with the back stock sight but the front sight is a must for EDC. The price of these is very reasonable and that front sight is so slick! Doesn't matter in sunlight of complete dark it's a top contender. Front sight install is very easy especially with the front sight tool but the rear sight is a diffrent story. I'm lucky enough to have a friend with a stationary vice so all I had to do was use two pieces of cardboard for the side of my slide (so it did not get marred or scratched up) and a punch and hammer. Done deal just take your time and don't get to frustrated if it doesnt seem like the rear sight isnt moving. It is it is just a tight right fit. Do it right or do it twice. And I read a review saying these were not LEGIT ameriglo night sights. THEY ARE! Especially the front. No tritium on the rear sight but I do not mind. A must have upgrade for any glock owners.

Turned my glock 19 into a surgical tool. I love this sight as its bright as easy to see. I can also approximate bullseye quickly, easily and repeatedly at 10, 15 and 25 yards.

Great sights, it’s kind of confusing trying to figure out if they fit Gen 5 9mm or not but they do just fine. I installed on a G47 with no issues.

For the money the sights are worth it. There’s a few pros and cons however I’d like to bring to light. PROs: solid construction and finish, tritium front sight is highly visible in low light situations, Price is hard to beat for the quality, Sight picture with U style notch rear and high visible front works great. CONs: front sight did not sit flush as there is room on either side of the sight when installed. When screwing in the sight it would shift right and come out of proper alignment to the rear sight. I had to physically correct it as I tightened which was a little frustrating. Time will tell if it shifts under heat and vibration. For the price I can’t complain too much though.

Great value for the money. Ameriglo makes some of the best sights on the market. This set also comes in orange-red if you're interested. As for the front, I feel it necessary to mention that it is more yellow than green. To my eyes at least. That being said, it's the brightest lime-yellow you'll find on the market. Bar none. As for the rear, it is a simple U notch. When ADS, there is some air on either side of the front but not much. There are no tritium vials in the rear, and that is why the price is lower than similar sights on the market. If this is a necessity to you, I suspect you're not even reading this review as you already moved on to something else. I too prefer tritium in my rear sights, but it is not so much of a necessity for me as to turn down a deal. Any concerns about night time shooting would be better spent choosing a weapon light for your particular Glock. I've used the same set of sights in orange-red on another gun to great effect in competition. I suspect these will be accurate as well on this particular 26 at least. For the more advanced reader that is wondering, these sights are comparable to 4.1 front and 6.1 rear OEM Glock sights, if you were wanting your POA/POI not to change. (Of course, that would only matter if your particular gun has 4.1 and 6.1 sights on it, you can tell the difference, and you're good enough to tell if it is shooting how you want it to shoot).
