The P320 XFULL is an XSeries, striker-fired, full-size 9mm built around SIG Sauer's modular design with a serialized stainless-steel fire control unit. It uses a 4.7 inch carbon steel, non-threaded barrel and a black Nitron-finished slide.
The slide includes front and rear cocking serrations and an optic cut, and this Professional Program package comes with a factory-installed SIG Sauer ROMEO-X reflex sight. Iron sights are retained, with a green dot front sight.
Ergonomics are anchored by the polymer XSeries grip module with molded texturing and an extended beavertail, plus the flat-faced XSeries trigger. An M1913 three-slot accessory rail is integrated into the dustcover.
