Description
AmeriGlo built the Protector set around one simple idea: get your eye on the front sight and keep it there. The green tritium front dot is wrapped in a bright LumiGreen photoluminescent ring that pops in daylight, while the tritium lamp underneath keeps glowing when the lights go out. Pair that with a flat black serrated rear and you get the kind of contrast that makes lining up a shot feel automatic, whether you're on the range at noon or clearing a dark hallway at 2 a.m.
Why the Protector Set Works on a Carry Glock
The blacked-out rear is the quiet hero here. Because it has no dots or distractions, your eye naturally drives to that glowing front sight instead of getting lost in a three-dot pattern. The rear notch is also serrated to cut glare under bright light, and those flat surfaces give you something to hook on a belt or holster edge for one-handed slide manipulation if your other hand is ever occupied. It's a setup a lot of carry-minded folks prefer over factory plastic sights.
Fit and Build of the Protector G/L Sights
This GL-705 set drops onto the Glock 42 and 43, and the same footprint also covers the 43X and 48. The front sight runs .140" wide, and the black rear gives you a clean square notch to frame it. Sights are precision machined from US made bar stock steel and assembled with genuine Swiss tritium light sources, so this is a legitimate night sight upgrade and not just a paint job. AmeriGlo has spent years working directly with pistol makers, and their gear is trusted by law enforcement, competitors, and everyday carriers alike.
Installation is straightforward with the right tools. A proper sight pusher makes the rear go on cleanly, and the front is a simple screw-in from underneath the slide. If you're not comfortable doing it yourself, any gunsmith can knock it out in a few minutes.

Frequently Asked Questions
Will the AmeriGlo Protector GL-705 sights fit more than just the Glock 42 and 43?
Yes. While this set is marketed for the Glock 42 and 43, it uses the same sight footprint that also fits the Glock 43X and 48. If you run any of those slim single-stack Glocks, this set will work for you.
Are these true night sights or just glow-in-the-dark paint?
These are genuine tritium night sights. The front dot uses a Swiss tritium lamp that glows on its own without needing a charge from a light source, so it stays visible in complete darkness. The LumiGreen outline around it is photoluminescent and brightens the daytime sight picture on top of the tritium.
Why does the Protector set use a blacked-out rear instead of a three-dot setup?
The plain black serrated rear is intentional. With no distracting rear dots, your eye is pulled straight to the bright front sight, which speeds up acquisition and helps you keep your focus where it belongs. It's a popular choice for defensive and carry use.
Can I install these myself?
You can if you have the right tools. The rear sight is best pressed on with a proper sight pusher to avoid marring the slide, and the front sight screws in from underneath. If you'd rather not risk it, a gunsmith can get them installed and confirmed quickly.
