The XSeries full-size configuration combines a 4.7 in barrel with a 17+1 capacity, flat-faced trigger, and the XSeries grip module featuring an extended beavertail and high undercut for secure control. Ambidextrous slide catch levers and a reversible magazine release support left- or right-handed use without changing the pistol's setup.
The slide wears SIG's Nitron black finish and includes front and rear cocking serrations plus an optic cut with the PRO footprint. Sighting is fast and clear thanks to XRAY3 day/night sights with a green-dot night front sight, complemented by the mounted ROMEO-X red-dot. The ROMEO-X provides dot or circle-dot reticle options in red and uses the PRO/DeltaPoint Pro footprint in a compact micro-reflex form factor.
Built on the modular P320 Fire Control Unit architecture, this striker-fired, short-recoil, locked-breech pistol allows straightforward configuration within the P320 ecosystem. A 3-slot MIL-STD-1913 accessory rail on the dustcover supports common duty accessories, while the XSeries grip module is accented with a SIG medallion.
