XS SIGHTSR3D Tritium Night Sight for Glocks Gen 1-5 and Taurus, Front and Rear Glow in The Dark Tritium for Tactical Applications

They're as described, but from the pics i had thought they were a 1/3 cowitness, and they are in fact too tall for that. They would have been absolute cowitness even if i used a plate instead of a milled slide

So far, so good. Installed them yesterday, tried them in very low-light conditions and found them obviously superior to the sights that came with the Glock 30S in late 2015. Since the half-life for tritium is 12.4-years, I suspect these will remain functional for at least that long. And that's ample, since I'm not sure I'll be around much longer than that. ;-)

Very fast sight acquisition

The good.I Really enjoy the durable feel and look of these sights.They stay glowing long after exposure to light has fade which makes it practical for night hikes and such. The badTheyre really quite sharp around the edges and I ended up filing them down slightly to not dig into my skin while seated and carrying.They rusted very easily so make sure you oil them up good a couple times to prevent rust because they come almost too clean from factory haha wish I would have bought a pistol sight tool when I purchased this though just some advice to others to plan ahead if youve never changed a sight. They fit tight and the proper tool is well worth it.

This is the first set of XS RAM sights I’ve purchased and I am quite happy. I’ve used XS Big Dots and DTX 2’s in the past and the RAM sights are up to the same quality. The orange ring around the front sight is easy to pick up in daylight and the tritium vials are middle-of-the-road in terms of brightness - not the brightest I've ever experienced but not the dimmest either. There is a decent amount of space on either side of the front sight within the sight picture. Too many sights these days leave little room between the front and rear sights which make it more difficult to get good alignment before a shot is taken. To be fair, I didn't exactly install these on a carry-length gun but the space should be fine at shorter barrel lengths. Also, these installed much more easily than some of my prior XS products. No sloppy rear sight combined with a ridiculously tight front sight fit here.

Very good bright front site that is easy to pick up at night. In the day, the rear tritium dots are nearly blacked out, which is what I like. My only gripe is the rear site is by now after a month starting to show rust on the right side & it is continuing to spread. I work mostly outdoors lately so my duty firearm is constantly being exposed to humid warm air. You may need to lube that rear site to protect it if you're going to be outdoors in summer.

I thought the front sight dot being larger than. The rear eould throw me off but it feels very natural. Good quality, are perfect brightness in dark settings and very easy to see during day. Used a sight press to install on a stock glock 19 slide, went on perfectly

These are nice sights. However, the rear sight required some filing to fit the dovetail. It is not difficult if you have any mechanical inclination and the proper tools. Once fit, the sights performed well, with the front sight easy to pickup being so large and bright. We shall see how they hold up long term.
