SIG SAUER P320 XTEN COMP 10MM | 3.8″ | 320XCA-10-COMP

The SIG SAUER P320 XTEN COMP is a carry-length, striker-fired 10mm pistol that pairs a compact XSeries grip module with a slide-integrated compensator and an optic-ready footprint. The design emphasizes controllability for a powerful cartridge while keeping capacity high in a compact package. It ships with two 15-round magazines and XRAY3 day/night sights to support rapid, reliable sight acquisition. For an optic under $1,000 that pairs well, consider the SIG SAUER ROMEO2 reflex sight, which is compatible with the P320 XTEN’s optic footprint.

Applications include backcountry hunting and extended outdoor trips such as hiking or fishing where a high-performance 10mm in a shorter package is desirable.

If you need a compact 10mm package with high magazine capacity and an optic-ready slide, this model delivers those capabilities in a durable, serviceable platform.
