Description
The AmeriGlo Protector set takes the classic three-dot clutter off your Glock and replaces it with a simpler, faster setup built around the front sight. Up front you get a green tritium lamp wrapped in a LumiGreen outline that glows for several minutes after a hit of light, so the post jumps out whether you are on an outdoor range in the sun or clearing a dark hallway at 2 a.m. The rear is left plain and blacked out, with serrations across the face to cut glare and keep your eye from getting pulled off the front dot.
What the Protector Setup Does on the Range
The whole idea here is front sight focus. With a single tritium vial up front and a clean black rear, your eye naturally settles on the glowing post instead of trying to line up three dots. That makes for quicker sight acquisition and a cleaner picture, which is exactly what you want for defensive shooting and everyday carry. Those rear serrations also do double duty, giving you a rough edge you can catch on a belt or holster for one-handed slide manipulation if you ever need it.
Build and Fit of the AmeriGlo Protector
These are machined from USA-made steel bar stock and wear a matte black, case-hardened finish that holds up to daily carry and hard use. The low-profile design with beveled edges helps keep the sights from snagging on cover garments, which conceal carry folks will appreciate. The tritium itself is Swiss-made, the same self-luminous technology trusted for serious duty use.
Glock Models the GL-701 Covers
This set fits a wide range of Gen 1 through 4 Glocks, including the 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. It is not cut for MOS slides. Installation calls for a proper sight pusher or a trip to your gunsmith, since driving these in by hand can damage them. Get them seated right and dialed in, and you have got a rugged, no-nonsense upgrade that outperforms factory plastic sights in just about every lighting condition.

Frequently Asked Questions
Will the AmeriGlo Protector sights fit my Glock?
This set is cut for Gen 1 through 4 Glocks, covering the 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. That includes the common 9mm, .40, and .380 models in those generations. Just note these are not made for MOS-equipped slides.
Does the rear sight glow in the dark too?
No, the rear is intentionally blacked out with no tritium. Only the front post has a tritium lamp. That is the whole point of the Protector design, since a plain rear keeps your eye locked on the glowing front sight for faster target acquisition in low light.
Can I install the Protector sights myself?
You can if you have a proper sight pusher tool, though the rear typically drives into the dovetail and the front usually attaches with a screw from underneath the slide. Trying to hammer them in without the right equipment can damage the sights. If you are not set up for it, having a gunsmith install and confirm zero is the safe route.
How long will the tritium stay bright?
The tritium front lamp is self-luminous and glows on its own without needing a light source, using the same Swiss-made technology trusted for duty use. Tritium naturally dims over roughly a decade or so as it decays. The LumiGreen paint outline is separate and charges up from ambient light to give an extra bright glow for several minutes after exposure.
