The XTEN COMP integrates an expansion-chamber compensator directly into the slide to help tame 10mm recoil, with SIG indicating about a 20% reduction in felt recoil. The slide wears a durable Nitron finish and includes front and rear serrations for confident manipulation.
Its PRO/R2 optics cut comes with a cover plate and rear sight installed and is compatible with SIG ROMEO2, ROMEO X Pro, and Leupold DeltaPoint Pro footprints. Factory SIG XRAY3 day/night tritium 3-dot sights provide a green tritium front dot with tritium rear, giving clear sight references in varied light.
A 3.8 in carbon steel bull barrel pairs with the striker-fired X-Series fire control and a flat trigger with a 90-degree break. The X-Series 10mm/.45-size carry grip module includes an M1913 accessory rail, and this compact-format pistol carries 15+1 rounds while maintaining everyday dimensions.
