The AmeriGlo Pro-Glo set takes your Glock from adequate to genuinely dialed in, day or night. It runs a classic three-dot layout: a green tritium front lamp wrapped in a bright LumiGreen outline that grabs your eye fast, plus two green tritium lamps with white outlines on the rear. In daylight the outlines give you the contrast you need, and once the sun drops the tritium keeps all three dots glowing so your sight picture never disappears.
These are cut from US-made bar stock steel and assembled with Swiss tritium, so they hold up to years of holstering, drawing, and range abuse. The rear features a squared-off ledge, which is handy if you ever need to rack the slide one-handed against a belt or boot. The tritium is warranted for 12 years, so you're not going to be second-guessing your dots anytime soon. The LumiGreen paint on the front also charges up under light and stays glowing for around ten minutes, giving you an extra visual boost in transitional lighting.
This GL-243 set is built for Gen 1 through 4 Glock 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. Front height runs .140 inches with a .180 inch rear notch, which is the standard configuration most folks want for a clean co-witness with the factory zero. It is not cut for MOS optic-equipped slides, so keep that in mind if you're running a red dot.
Most people find the front sight simple to swap with a hex nut driver and a dab of thread locker. The rear is a tight press fit, which is exactly what you want since it won't drift under recoil, but you'll want a sight pusher or a brass punch and patience rather than brute force. If you're not comfortable doing it yourself, any local gunsmith can knock it out in a few minutes.
Yes, the GL-243 set is made for Gen 1 through 4 Glock 17 and 19, along with the 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, and 39. It is not cut for MOS optic slides, so if your Glock has a red dot mount you'll want a different set. Double check your generation and model before ordering to make sure you're covered.
The front sight is a straightforward swap with a hex nut driver and a little thread locker, and most people handle it at home. The rear is a tight press fit, so a sight pusher tool or a brass punch and some patience is the way to go rather than forcing it. That snug fit is actually a plus, since it keeps the rear from drifting under recoil. If you'd rather not tackle it yourself, a gunsmith can install the set in minutes.
The green tritium lamps are warranted for 12 years from the date of manufacture, so you get well over a decade of low-light glow before you'd think about replacing them. On top of the tritium, the LumiGreen front outline charges under light and keeps glowing for roughly ten minutes, giving you extra visibility in changing conditions.
The front sight uses a single green tritium lamp inside a high-visibility LumiGreen outline to pull your eye straight to it. The rear has two green tritium lamps with white outlines for a clean three-dot picture and quick alignment. The green-on-green setup is easy to lock onto in the dark, while the contrasting front outline helps in daylight.
