Description
Slim single-stack Glocks like the 42, 43, and 43X are some of the most carried pistols out there, and the factory plastic sights don't do them justice. The Night Fision GLK003007YGZ swaps those out for a real front and rear tritium set that lights up when the sun goes down and stays sharp in broad daylight. The front sight runs green tritium wrapped in a bright yellow outline, and the rear is a green tritium U-notch with a blacked-out ring so your focus lands where it should.
What Sets the Night Fision Perfect Dot Apart
Most night sights use aluminum sleeves and a painted-on white ring around the vial. Night Fision took a different route with a patented injection molded sleeve that locks the tritium vial in place and forms a more durable, higher-contrast ring they call the Perfect Dot. On top of that sits a domed lens that focuses the tritium light into a crisp, defined glow instead of a fuzzy blob, which makes for a cleaner sight picture in low light.
Build Quality on the GLK003007YGZ Sight Set
These are CNC machined from steel and finished in Black Nitride, so they hold up to holster wear, sweat, and the daily grind of carry without looking beat up after a month. The tritium vials are sourced from Switzerland, and outside of those vials the sights are made in the USA. It's a combination that gives you serious daytime visibility from that yellow front ring plus dependable glow at night.
Getting Them Dialed In
The front sits at 0.213 inches tall with a 0.140 blade width, and the rear comes in at 0.240 inches. This is a drop-in replacement for the OEM sights, though a sight pusher or a trip to your local gunsmith makes install painless and keeps everything square. Folks running these on a 43 love how the big front dot grabs the eye fast and the U-notch frames it perfectly for quick, repeatable alignment.

Frequently Asked Questions
Will the Night Fision GLK003007YGZ fit my Glock 43X?
Yes, this set is designed for the Glock 42, 43, and 43X. It uses the standard front post and rear dovetail mount for those slim single-stack models. Just make sure your pistol is one of those three and you're good to go.
Are these tritium sights bright enough for carry use?
They are. Night Fision packs more tritium than the average night sight and uses a domed lens to focus that glow into a sharp, defined dot rather than a soft haze. The yellow front outline also makes the front sight jump out during daylight, which is a big help for fast target acquisition.
Can I install the GLK003007YGZ sights myself?
You can if you have a sight pusher tool, since these are a direct replacement for the factory sights. That said, a gunsmith is recommended for a clean, properly centered install, especially for the front sight. Getting them squared away right matters for accuracy.
How long does the tritium last on these sights?
Tritium has a half-life of around 12 years, so you can expect strong, usable glow for well over a decade of everyday carry. The vials will gradually dim over time rather than switching off suddenly. Night Fision sources their tritium from Switzerland, which is known for consistent quality.
