The X-Series XFULL configuration delivers a full-size 9mm layout with a 4.7 in barrel and 17+1 capacity. This model is striker-fired and semi-automatic with no external manual safety, and it uses a left-side magazine release.
The X-Series full-size grip module incorporates an extended beavertail and a high undercut to promote control, along with molded texturing for a secure hold. A flat-faced trigger complements the setup with a straight, consistent press.
The black slide includes front and rear cocking serrations for positive manipulation. It is optics-ready, machined with an optics cut and cover plate, and uses a removable rear-sight plate. Sights are 3-dot night sights with a high-visibility green front dot and a night rear sight on the removable plate.
Construction centers on SIG Sauer's modular, serialized stainless-steel FCU seated in a black polymer frame with a stainless-steel receiver. An M1913/Picatinny accessory rail with three slots provides space for compatible lights or accessories. This pistol is made in the USA and ships with three 17-round magazines in the factory case.
