When you mount a red dot or thread on a suppressor, your factory Glock irons disappear behind the optic or under the can. The AmeriGlo GL333 fixes that. This XL Tall set sits high enough to give you a clean lower-third co-witness through most slide-mounted optics, and it clears the taller sight line a suppressor demands. If your dot ever goes dark, these irons are right there waiting.
Up front you get a green tritium lamp wrapped in a LumiGreen outline, which soaks up light and keeps glowing for a good while after the lights go out. The rear pairs a green tritium lamp with a plain white outline, so your eye naturally lands on the front post and lines things up quick. Tritium handles the pitch-black work while the painted outlines carry you through daylight and dusk. AmeriGlo uses Swiss-made tritium, and the whole set is CNC machined from steel with a matte black finish that won't throw glare back at you.
The front measures .315 inches and the rear comes in at .394 inches, putting this squarely in AmeriGlo's XL Tall category. It drops into most Glock Gen 1 through 5 pistols, including MOS models, covering the 17, 19, 26, 34, 20, 21, and plenty more. The two models it does not fit are the 42, 43, 43X, and 48. The elevated deck height is also matched to popular optic footprints like the Aimpoint Acro, Holosun 509T, and Steiner MPS.
Swapping sights on a Glock is a straightforward job with the right tools, though a sight pusher makes the rear go a lot smoother than a punch and hammer. Now and then a dovetail runs a touch tight and needs a light pass to seat perfectly, which is normal when you're fitting quality steel sights. Once they're in and zeroed, they hold up to recoil, holster wear, and hard use without fading on you.
Yes, that's exactly what this XL Tall set is built for. The elevated deck height gives you a lower-third co-witness through most slide-mounted optics, so your irons show up in the bottom of the window. It's designed around footprints like the Aimpoint Acro, Holosun 509T, and Steiner MPS.
It does. The suppressor-height design raises the sight line enough to clear most cans, letting you actually see and use your irons with a suppressor mounted. That same tall profile is what makes it double as an optic co-witness set.
It covers the bulk of the Glock lineup across Gen 1 through 5, including MOS slides, so the 17, 19, 26, 34, 20, 21 and many others are good to go. The exceptions are the 42, 43, 43X, and 48, which use a different sight footprint. Always match the set to your specific model before ordering.
Yes, both front and rear use green tritium lamps that glow on their own in total darkness, no charging needed. The LumiGreen front outline adds a photoluminescent boost that stays lit for a while after light exposure. Tritium slowly dims over its service life, but you'll get many years of dependable low-light performance.
Plenty of folks do it at home, though a proper sight pusher makes the rear far easier and safer than a brass punch. The front typically uses the Glock sight tool for the hex screw underneath. If a dovetail runs tight, a light fitting pass is normal, but if you're not comfortable, a gunsmith can knock it out fast.
