FAQ
Is this pistol compatible with standard P320 holsters?
Yes, the WCP320 uses a standard P320 full-size frame and slide profile, so it fits most P320 holsters. However, holsters with tight retention may require slight break-in due to the Wilson Combat grip texture.
Can I use aftermarket P320 magazines with this gun?
Yes, the WCP320 accepts all factory SIG Sauer P320 magazines, including 17-round, 21-round, and 10-round models. The included X-Series magazines are standard P320 mags with a basepad that works with the Wilson Combat grip.
Is the trigger upgraded from a stock P320?
The trigger is the same SIG Sauer flat trigger found on the X-Series P320. It offers a crisp break and short reset. Wilson Combat does not modify the trigger assembly on the WCP320, but you can upgrade it later if desired.
Does this pistol come with a case or lock?
Yes, the WCP320 ships in a hard plastic case with a cable lock, two 17-round magazines, and a manual. It’s ready for safe transport and storage.
Is the DLC finish safe for holster use?
Yes, the black DLC coating is extremely hard and resistant to holster wear. It will hold up well with regular use, though like any finish, it may show slight wear over time if used with abrasive holsters.
