Description
The TRUGLO Tritium Pro set is a big step up from the plastic sights that ship on most Glocks. You get a square white-outline front paired with a green tritium rear, so you have a sharp reference point in broad daylight and a self-glowing dot picture when the sun goes down. Tritium does the work on its own, meaning no batteries to swap and no need to charge them under a light. It just glows when you need it.
What Makes the Tritium Pro High MOS Set Different
This is the taller "High" MOS version, built to sit up over a mounted red dot for a lower 1/3 co-witness and to clear taller muzzle devices. The rear uses TRUGLO's quick U-notch design that makes it easy to catch the front sight fast, and there's an angled front edge on the rear sight so you can rack the slide one-handed off a belt or holster in a pinch. The front sight carries a white Focus Lock ring that pulls your eye right where it needs to be.
Built Tough for Everyday Carry
These are machined from solid steel and treated with TRUGLO's nitride Fortress Finish, so they hold up to holster wear, sweat, and the kind of abuse a carry gun sees. The tritium is quality Swiss material assembled in the USA, and the slim, snag-resistant shape slides in and out of standard holsters without catching.
Fitment for Glock MOS Models
This set is cut for the High MOS lineup, covering Glock 20, 21, 25, 29, 30, 31, 32, 37, 40, and 41. If you run one of the larger frame MOS pistols and want a night sight that co-witnesses cleanly with your optic, this is the one to grab. Sight installation is best handled with a proper sight pusher or by a gunsmith to keep everything seated square and zeroed.

Frequently Asked Questions
Will these Tritium Pro sights co-witness with my Glock MOS red dot?
Yes, this is the taller High MOS profile, so it sits up over a slide-mounted optic for a lower 1/3 co-witness. Users running setups like a Holosun on a G45 MOS report a clean, spot-on co-witness. The same height also lets you see over most suppressors and taller muzzle devices.
Do the TRUGLO Tritium Pro sights need batteries or charging?
No. The green glow comes from tritium, which lights up on its own and does not need batteries or a charge from a flashlight. During the day they read as standard white dots, then transition to glowing green in low light and full darkness.
Which Glock models does this High MOS set fit?
This set is cut for the High MOS lineup, covering Glock 20, 21, 25, 29, 30, 31, 32, 37, 40, and 41. Since MOS pistols vary, it is worth confirming your exact model and slide cut before ordering. If you run a standard-height MOS like a 17 or 19 MOS, you would want the Low version instead.
Are these easy to install at home?
The front seats on the front post and the rear drops into the dovetail, which is a straightforward job with the right tools. A sight pusher makes the rear go in clean and lets you drift it for windage, and many folks have their gunsmith handle it to keep everything square and zeroed. The steel build and Fortress finish hold up well once they are in place.
