Tritium dots and black notch design

Ameriglo's two-dot tritium system delivers consistent visibility without batteries or external light sources. The green tritium dots glow continuously, while the black notch provides a defined sight picture during daylight and transitional light. This sight mounts directly to Sig Sauer, Springfield XD, and Hellcat (non-OSP) frames. If you're building a defensive or range firearm, check our California-compliant handgun catalog for compatible platforms. Browse our gun store.

Frequently asked questions

Will this rear sight fit my Hellcat slide?

Yes, this sight is cut for non-OSP Hellcat models. If your Hellcat has an optical sight cut (OSP), this sight will not fit. Verify your slide type before ordering.

How long do tritium sights stay bright?

Tritium has a half-life of approximately 12 years, meaning brightness gradually decreases over time. Most shooters find them usable well beyond the first decade with regular nighttime training.

What is an FFL transfer in California?

An FFL transfer is when a federally-licensed dealer like TacticCAL receives a firearm shipped from another seller and processes California's required DROS paperwork to legally transfer it to you. Find FFL dealer Cupertino at TacticCAL.
