Ameriglo 4XL Tritium Night Sight Set for Glock Green with White Front Black Rear

Upgrading your Glock's low-light performance starts with quality night sights. This Ameriglo 4XL tritium set pairs a bright green front sight with a blacked-out rear, giving you rapid target acquisition in darkness. Whether you're in San Mateo or Sunnyvale, TacticCAL handles your FFL transfer in Sunnyvale and can help you build the carry gun you need.

Tritium illumination and sight picture design

The 4XL profile delivers a wide field of view without sacrificing precision. Green tritium in the front sight creates a natural aiming reference, while the white outline on that front post aids daylight shooting. The blacked-out rear keeps your focus downrange. These sights work with optic-ready Glock slides if you're building a dual-sight setup. For shooters handling private party transfer process pistols, night sights are often the first upgrade. TacticCAL is your local firearms dealer in the Bay Area.

Frequently asked questions

Will these sights fit all Glock models?

These are designed for standard Glock dovetails. Most full-size and compact Glocks accept them directly. Check your specific model's manual or contact our team to confirm fitment before purchasing.

How long does tritium glow last?

Tritium has a half-life of about 12 years. You'll see strong glow for roughly a decade, with gradual dimming afterward. Most shooters replace sights before tritium becomes dim.

Does TacticCAL help with CA compliant firearms?

Yes — TacticCAL specializes in California-compliant handguns from the DOJ Roster and PC §32100 exempt single-action revolvers. TacticCAL is your gun shop Campbell in the Bay Area.
