Frequently asked questions

Will these sights fit my Glock 43x slide without modifications?

These sights are engineered for the Glock MOS footprint. You'll need an MOS-compatible slide to mount them directly. Standard 43x slides require different sight systems.

How bright is the fiber optic front sight in indoor ranges?

The orange fiber optic collects ambient light effectively indoors, though brightness depends on available light. The tritium rear sight functions regardless of lighting conditions.

How long is the California firearm waiting period?

California requires a 10-day waiting period from when DROS is submitted until you can take possession of the firearm. Find gun shop Mountain View at TacticCAL.
