Sights for Sig Sauer P320 Optics Ready

This collection covers sights made to fit the Sig Sauer P320 Optics Ready, part of Sig Sauer's long-running P-series and P320/P365 duty and carry range.

A co-witness set means the dot and the irons share the same window - if the optic goes down mid-string, the front post is already sitting where you're looking, with no need to re-index onto a separate sight picture.

Stocked as matched front-and-rear sets, semi-adjustable co-witness sets (fixed front, windage-adjustable rear, co-witness height). Illumination options include fiber optic, tritium, luminescent dots, white dots.

Fiber optic front sights gather ambient light along a thin rod and glow at the tip - fast to find in daylight, which is why most competition shooters run one on the front post. Tritium sights use a sealed, self-illuminating gas vial instead, holding a visible sight picture in the dark with no battery to charge.

Whichever illumination you pick, the co-witness height is what matters most here - it's what keeps the sight picture aligned with the optic's window. Fiber optic makes that backup picture easier to find quickly; tritium keeps it visible if you also carry the gun after dark.

Sourced from LPA (Italy), Angry Bear (USA), and Night Fision (USA).
