SIG Sauer P320 Carry 9 mm Luger – Wilson Combat WCP320 Grip Module, Night Sights, 21-Round Capacity
Built around SIG Sauer’s serialized, modular fire-control unit and upgraded with Wilson Combat’s WCP320 Carry grip module, this P320 brings a custom-shop feel to a proven striker-fired platform. The compact 3.9" Nitron-finished carbon-steel barrel, factory night sights, and generous 21-round magazines give you full-size performance in a carry-friendly footprint—making this example equally appealing to dedicated SIG users, collectors of modern service pistols, and anyone who appreciates a well-executed customization.
Condition
Excellent overall. The slide and barrel retain a deep, even Nitron finish with only a few faint handling marks visible under close inspection. Wilson Combat’s polymer grip shows crisp starburst texturing with no smoothing or scratches. Internally, the upgraded post-2018 fire-control unit (serial prefix T6-) is clean and unmarred. The bore is bright and mirror-smooth; six-groove rifling remains sharp from throat to crown.
All controls cycle positively, and dry-fire checks reveal a clean, consistent break—exactly what you expect from a lightly-used, well-maintained P320.
What’s Included
• SIG Sauer factory hard case with matching serial label
• SIG Sauer P320 operator’s manual
• Two steel 21-round Mec-Gar/SIG magazines and one 17-round magazine, all “MADE IN ITALY” marked
The Wilson Combat WCP320 Carry grip module is more than cosmetic. Its 1911-inspired grip angle, high under-cut trigger guard, and tungsten-weight channels tighten groups and speed follow-up shots. Paired with the P320’s reversible magazine release and fully ambidextrous slide-stop levers (included on the FCU), the pistol adapts easily to right- or left-handed use.
Factory three-dot tritium night sights offer a bright green front lamp and two rear dots for fast alignment in any lighting. The slide’s forward and rear cocking serrations provide a positive grasp, while the external extractor doubles as a loaded-chamber indicator. Although SIG designs the P320 around a chassis, this example’s slide remains uncut, giving you the option to mill for your preferred red-dot; it already accepts SIG PRO-footprint optics after aftermarket machining.
Inside, the striker-fired action incorporates a striker safety, disconnect safety, and articulated trigger tab—passive systems that work unobtrusively in every shot cycle. The full MIL-STD-1913 dust-cover rail supports weapon lights or lasers without the need for proprietary adapters.
Whether you’re seeking a duty-grade sidearm with enhanced ergonomics, a modular base for future caliber or size conversions, or simply a refined example of SIG’s flagship striker pistol, this P320 Carry checks the boxes with minimal rounds and premium upgrades already in place. Consider adding it to your lineup while it’s available.
