HIVIZ Sight Systems GLT178, Glock Target Sight Set

Installed these on my Glock-style build and I couldn't be happier. Nice metal sights with good and bright Fiber rods. I've seen similar quality sight sets on sale for $100+ and chuckle when I think this was so cheap but just a good (if not better) than the $100+ sets....

threw these on a glock 19 slide. they went on a lot tighter than trijicons i've put on in the past. because front sight is so long, it was a challenge to get it lined up perfectly. its length does make it easier to tell if it is misaligned though. used blue loctite and its on there very nicely. rear sights have a set screw, so i would expect them to be near the same size as factory or smaller. these were a little bit bigger. i didnt wanna grind off any material so i pushed them on. ended up having to use a punch because my cheapo sight pusher looked like it was gonna break. the sights themselves look great once on there. i heard that they take ambient light through the tubes very well at night time, but not the case for me. in the few situations i tried in low light, only a flashlight held up overhead gave these any good illumination. daytime use, they look awesome and are very clear, definitely better than tritiums, but for night time use, nothing will beat tritium.

What I like about this sight is that the fiber-optic tube is almost entirely exposed thus letting in more light to really brighten the sights. I was about to initially get the Truglo but I noticed their sight is a lot more dim than HiViz due to their housing covering and wrapping around the fiber-optic which prevents the light from powering up the sights.The front sight was a breeze to install using the glock screw driver. The rear sight install was pretty stubborn. I have a pistol sight tool which really helped but it took quite of bit of straight to screw the sight in.Overall great product. I will purchase again for my other pistols.

The sights made a big difference during outdoor shooting they really light up nice. Easy to get on target for these old eyes. I had night sights on my Glock 19 but I shoot mainly outdoors so I went with the Hiviz fiber Optics, big difference. The only problem was the installation...the front sight no problem with the Glock wrench but the rear sight was a different story. It would not fit and I tried sanding still wouldn't fit then I tried filing but I had to file a lot off to get it to fit. Even with all the filing it fits real tight. I would have given 5 stars except for the installation.Nick C.

POI is on at 10 yards on my G17, center hold. Colors are swappable; I prefer red front, green rear. Fiber optic rods have stayed put through several hundred rounds so far. Remember to loosen the rear set screw before adjusting windage.

Got these bad boys for only 30 bucks. He'll of a time getting old sights out. And these slide in tight smooth. Love that colors are interchangeable. I did red green in back and white up front. I put these on my 5.7 rock

It shows it comes with 2 rear black sights…. The ones I bought a year ago did. These did not. Disappointed

After installation I noticed the front sight was not parallel to the slide. So I straitened it. In the process it dawned on me this means some windage adjustment can be done quickly and easily by twisting the front as opposed to drifting the rear, which is a more interesting task. So yes, I highly recommend using locktite on the front sight screw. As others have said these are daytime sights, not night sights. That said, in any kind of sunlight, a blind person could use them. One warning: you want to google the part number to get an accurate description of what they fit and what spare pipes are included, as the description is woefully deficient. Mine came with these extra pipes: 1 white and 2 black (both opaque, not fiber optic), 2 green and 1 red (both fiber optic).
