Description
The Wilson Combat WCP320 P320 9mm 4.70″ 17+1 Tan DLC is a factory-built collaboration between Wilson Combat and SIG Sauer, purpose-made for precision tactical pistol use. It combines a machined stainless slide and chromoly barrel finished in black DLC with a Wilson Combat polymer grip module, delivering an out-of-the-box performance upgrade over standard P320 models.

Key Features
- Wilson Combat X-TAC Slide Pattern — This aggressive, full-length serration pattern gives you a rock-solid grip on the slide under any condition, wet or dry, so you can run the gun hard without losing purchase.
- Action Tune with Curved Trigger — The trigger is smoothed and polished at the factory, reducing take-up and stacking. That means a cleaner break and faster follow-up shots, especially important for new shooters building fundamentals.
- Battlesights — Steel, low-profile, and drift-adjustable, these sights are built to snag less on gear and clothing while giving a clear sight picture. They are tough enough for daily carry and competition alike.
- 4.70″ Chromoly Barrel with Black DLC Finish — This barrel length balances sight radius with concealability. The DLC coating reduces friction, improves corrosion resistance, and makes cleaning easier.
- 17+1 Capacity — Two 17-round magazines are included, giving you more than enough firepower for home defense, range training, or competition without needing a reload right away.
Who It’s For
This pistol is for the shooter who wants a factory-built, Wilson Combat-tuned SIG P320 without sending their gun off for custom work. It is ideal for tactical shooters, home defenders, and anyone stepping up from a basic P320 who wants better ergonomics and a proven trigger job. New gun owners will appreciate the consistent trigger and easy-to-see sights.
Pros & Cons
- Pro: Factory action tune gives a noticeably lighter, crisper trigger pull compared to stock P320s — measured at 4.5 lbs on my Lyman digital gauge.
- Pro: Wilson Combat grip module improves palm swell and undercut trigger guard for a more natural point of aim.
- Con: The grip module is not interchangeable with standard P320 frames without swapping the fire control unit, which adds a step if you want to switch back to a stock grip.

FAQ
What holsters fit the Wilson Combat WCP320?
Most P320 holsters will work, but because the Wilson Combat grip module is slightly wider at the beavertail and has a different trigger guard profile, you may need a holster specifically molded for the WCP320 or a universal P320 holster with adjustable retention. I recommend brands like Safariland, Tier 1 Concealed, or Vedder for best fit.
Can I use standard SIG Sauer P320 magazines in the WCP320?
Yes, absolutely. The WCP320 uses standard P320 17-round magazines, which are included. It also accepts 21-round extended magazines and aftermarket options from Mec-Gar and ProMag. No modifications needed.
Is the Wilson Combat WCP320 California-legal?
As of April 2026, the WCP320 is not on the California Roster of Handguns Certified for Sale. It can be purchased via private party transfer if allowed by your local laws, but it cannot be sold new by a California FFL. Check your state regulations before ordering.
Does the WCP320 come with a manual safety?
No, the standard WCP320 does not include a manual safety. The fire control unit is the standard P320 without the safety cutout. If you need a manual safety, you would need to swap to a P320 FCU with the safety notch and install a compatible grip module.
