Excellent Tritium Fiberoptic Sight, Might Require Elevation Adjustment

This Glock HIGH TFO set replaced an older one on a Gen3 Glock21 that's tritium lost its luminosity over time. (The fiberoptic portion was still fine.) The new front sight is identical and the rear sight's height is the same as the older version but it is narrower. I rate it at only 4/5 because TruGlo's elevation point-of-impact is often not correct as they come and might require shimming.

Check your slide first

Only 4 stars but it's probably not the sights fault. Think about your slide first. I didn't. The rear sight sits over the RMR cutout on my slide. Not a problem since I'd probably replace the sights with suppressor height sights if I installed an optic. Also, the front sight is long, so if you have any cutouts on the top of your slide, it might look weird. The screw that came installed in the front sight wouldn't completely tighten the sight. Fortunately, they provided a second, shorter screw in the package for just this condition. After installing the shorter screw, it tightened down perfect. Don't forget blue loctite. Not sure I like this yet, but the yellow rear sights are slightly brighter than the green front sight in dark conditions. I'd rather have it the other way around.

TFO FIBER OPTIC

Great during low light and daylight shooting. Not so much, at night.

Good, but....

I have several sets of these on Glocks. They are easy to see for tired eyes and are the brightest I've found. However, for close to the body carry, they rust easily. I used automotive rust converter to prime them and painted them flat black. Have to touch them up about once a month.

Careful Installation = Great Sights

These sights show up great compared to nonfiber optic sights, as if they are lit up during day. Glow plenty bright at night, not as bright as standard night sights, but plenty bright. Only issue is these sights A.Sometimes fall out, so you need to epoxy or nail polish them in place, B. Can have problems with gun solvent, C. Break easily during install. Make sure they are installed with sight pusher!!
