Sig Sauer P320 X-Compact 9mm, X-Series, Optics-Ready Pro/R2 Slide, Tritium Night Sights, 3.6 in Barrel, 15+1, 2 Mags
This Sig Sauer P320 X-Compact is a compact 9mm built on the P320 modular platform with a serialized stainless-steel FCU, a 3.6 in barrel, and 15+1 capacity. It features an optics-ready Pro/R2-style slide that retains a dovetailed rear sight, factory tritium night sights with a TG-H3-marked front, and the X-Series flat-faced trigger and grip module. It comes with two 15-round steel magazines, the SIG SAUER factory hard case, and the owner's manual. Made in the USA with frame markings for Newington, NH.
The X-Compact configuration pairs a compact slide and barrel with the X-Series grip module for a carry-friendly footprint and enhanced control. The flat-faced X-Series trigger offers a consistent, straight press typical of the series, and the striker-fired action delivers familiar P320 operation.
Sight configuration is fully night-ready, with a tritium front sight marked TG-H3 and a two-dot tritium rear sight. The optics-ready Pro/R2-style slide uses a removable rear-sight plate while keeping a traditional dovetail, preserving sight options alongside mounting capability.
Construction includes a polymer grip module surrounding the serialized stainless-steel fire control unit, underscoring the P320's modular design. An integral accessory rail with four Picatinny slots provides mounting space. Magazines are steel and marked "MADE IN ITALY," and the pistol is identified by SIG SAUER part number L320C-9-BXR3-PRO.
