The XSeries XFULL Pro format delivers a full-size grip module with an extended beavertail and high undercut for consistent control. Its flat-faced XSeries trigger, semiautomatic striker-fired action, and modular stainless-steel serialized FCU anchor the platform's clean break and service-focused design.
The stainless slide wears a Nitron finish and includes front and rear cocking serrations, a bull-nose front profile, and an optic cut with plate. Sighting is handled by SIG XRAY3 day/night steel sights, pairing a high-visibility green front dot with a steel rear mounted on the optic plate. A factory-installed SIG Sauer ROMEO-X red dot completes the sighting setup.
