The XSeries XFULL configuration delivers a full-size 9mm setup with a 4.7 inch barrel and 17+1 capacity. The XSeries grip module features an extended beavertail and a high undercut to promote a stable, high grip.
The slide is finished in matte black with front and rear serrations for positive manipulation. It includes an optics-ready cut with the rear sight mounted to a removable optic plate, providing flexibility for mounting an optic if desired.
The striker-fired action pairs with a flat-faced trigger that promotes a consistent, straight press. This model has no external manual safety.
SIG XRAY day/night sights come installed, with a green tritium front dot and a two-dot tritium rear on the optic-plate unit for visibility in varied light. An integral three-slot Picatinny accessory rail supports lights or other accessories.
The modular P320 design centers on a serialized stainless-steel Fire Control Unit housed in a polymer grip module and stainless receiver components, allowing configuration changes within the P320 ecosystem.
