    This SIG SAUER P320 XCompact stands out as a well-equipped XSeries pistol with a 3.6 in barrel, stainless-steel slide, and serialized stainless-steel FCU in the modular P320 platform. It comes mounted with a SIG SAUER ROMEO1 PRO open-reflex red dot using a 6-MOA reticle and protective shroud, and includes both 17- and 15-round steel magazines. XSeries ergonomics with a beavertail and deep undercut, plus a flat, skeletonized trigger, round out a compact package built for control and speed.

    What’s Included
    • SIG SAUER P320 XCompact 9mm pistol
    • SIG SAUER ROMEO1 PRO red-dot sight (6-MOA), open-reflex, with protective shroud (mounted)
    • One 17-round steel magazine
    • One 15-round steel magazine

    The XCompact configuration pairs a 3.6 in barrel with the XSeries compact grip module featuring a beavertail and deep trigger-guard undercut. The flat, skeletonized trigger and striker-fired action provide a consistent break within the P320 system.

    The slide is stainless steel with front and rear serrations and an optic cut. Iron sights include a front blade with a bright green dot and a rear notch for a clear reference alongside the mounted optic. A MIL-STD-1913 rail with four slots on the dust cover supports accessories.

    The mounted SIG SAUER ROMEO1 PRO open-reflex optic offers a 1x view and uses a 6-MOA red dot for rapid acquisition. A protective shroud is included to help shield the sight body.

    Construction centers on a stainless-steel slide and a serialized stainless-steel fire control unit within the modular P320 design, allowing slide and grip-module swaps. As configured, capacity is up to 17+1, and this pistol ships with one 17-round and one 15-round steel magazine. Made in the USA.
