Frequently asked questions

What makes the 4XL different from standard Ameriglo night sights?

The 4XL features a larger front post and extended sight radius compared to Ameriglo's standard line, improving sight picture clarity and target focus in low light. The green tritium front contrasts sharply against the black rear for faster sight alignment.

Do these sights work on all Glock models?

These sights fit Glock pistols with standard dovetail cuts. Check your Glock generation and model before ordering. Glock 42, 43, and some compact models may require different sight models due to unique dovetail specifications.

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. TacticCAL is your gun store Los Gatos in the Bay Area.
