SIG Sauer has entered a new category of pistol optics with the XRAY5, a reflex sight built around a fixed 15-by-15 matrix of 225 individually addressable dots rather than the moving emitter found in conventional red dots. The Firearm Blog published a detailed technical breakdown of the optic this week, and SIG has begun listing the XRAY5 across its retail channel in Compact, Enclosed Compact, and Pro footprint configurations, starting at $499.99.

SIG Sauer XRAY5 Pistol Red Dot

1x solid-state 3.5 MOA red dot, sealed optic, multiple footprints

Where a standard red dot physically moves an LED emitter to adjust zero, the XRAY5 changes zero by selecting a different dot in the matrix — a system SIG calls Digital Zero. The company says the design eliminates the mechanical components responsible for zero shift under repeated recoil or temperature extremes. Soldier Systems first covered the XRAY5 when SIG unveiled it in late September, and since then the optic has drawn sustained attention for its departure from more than two decades of moving-emitter pistol sight design.

SIG rates the XRAY5 at IPX8 waterproofing, with a sealed rear optical window and an argon gas-purged lens system. The company says the optic has been tested through more than 100,000 consecutive live-fire rounds without a failure or loss of zero — a manufacturer claim that independent reviewers have not yet verified at scale. The dot measures 3.5 MOA, and brightness is adjustable through two side-mounted buttons or through SIG's companion mobile app, which also handles windage and elevation adjustments and a lockout mode that prevents inadvertent setting changes in the field.

Three footprint variants are currently listed. The Compact version at $549.99 fits the standard compact footprint common across most optics-ready handguns. The Enclosed Compact at $499.99 adds a fully enclosed optical window for additional debris protection. The Pro version, also at $549.99, targets competitive shooters and duty users with a wider sight picture. A SIG-LOC footprint version compatible with SIG's P-series handguns is expected to follow.

RECOIL magazine evaluated the XRAY5 as part of a combined pistol and weapon-light package alongside SIG's FOXTROT2R, suggesting that SIG is positioning the optic as an anchor component in a broader system-ready pistol setup. That pairing approach mirrors how SIG has built out the Romeo line — starting with the optic and expanding to a full accessory ecosystem.

The broader optics industry will be watching closely. Conventional pistol red dots from Aimpoint, Holosun, Trijicon, and others still use the same core moving-emitter design that the XRAY5 claims to replace. Whether the solid-state approach holds up under real-world conditions — sustained carry, temperature extremes, and the sharper recoil signature of suppressor-heavy pistol builds — will become clearer as first-look range reports and longer-term duty evaluations accumulate over the next several months.

Retail availability is still building, with multiple vendors listing the XRAY5 as arriving shortly. Expect broader in-store inventory before the holiday buying window closes.
