Tritium Pro Night Sights, Compatible with Glock Handgun Models | Compact Durable Glow-in-The-Dark Front & Rear Gun Sight Set with Focus Lock Front Ring

Great accessorie for your Glock handgun. Being able to accurately aim in the dark is a must.

Best purchase works great. Constantly maintains a picture sight with the glow that works even when it has been concealed and not exposed to light.

Note that these are for larger caliber Glocks. That was not apparent to me from the Amazon listing description. I believe the only place that I noted that, after the fact, was on a chart in the ad images. Because these were tritium they could not be returned. I would have been incredibly upset, but I am giving five stars because my money was refunded anyway, after attempting to return. I don’t know whether this was because I am a prime member and purchased lots of stuff from Amazon, or this was a concession that the vendor made, but I know that somebody cared about customer satisfaction making me pleasantly surprised. After some research, I learned that the reason these do not fit 9 mm and smaller calibers is the site height is slightly different than large larger calibers. That said these are great sites. All metal construction the dots are bright. I would not hesitate to purchase these and install them on a .40 S&W, 10mm, or .45 ACP Glock.

Great sights...much better than the originals. Easy to install...great buy! Looks great on my G20!

Great suppressor height sights. Now able to co-witness my Osight XR to my Glock 19 gen 6.

Installed on a G19 Gen 6. Appears to be well made. Easy installation using the right tool. But if you want bright tritium inserts you may be disappointed. Or, maybe the inserts just are not large enough. Either way, they are not as large/bright as the NS on other pistols I have that include Sig, FN, and PSA Dagger.

Amazing prayer for my Glock 23 fix fine always brighten the night. That’s exactly what I need.

Excellent product fits well on the Walther PD 380, some gunsmithing on the sight for proper fitment but works well! Sight visibility is excellent in minimal light or daylight use.

Truglo sights are good per my usual experience with their products. I have a G45 MOS and put the sights on with a Vortex Venom 6 MOA. They will work great as backup sights if the optic fails. From the one photo, you will see they do not do an absolute Co-Witness, you have them in the lower approx 1/3.
