What’s Included

- Four 17-round SIG Sauer steel magazines (one fitted with a Strike Industries basepad extension)
The serialized stainless-steel fire control unit (FCU) at the heart of the P320 is the legally regulated component, allowing caliber or frame size swaps without an additional FFL transfer. This pistol’s FCU is numbered 58J094441 and is housed in a Wilson Combat WCP320 full-size grip module featuring starburst texturing, a high-cut beavertail, and a lightly flared magwell for faster reloads.
Manipulation is further improved by Wilson Combat’s oversize takedown/slide-catch lever, giving the shooter a larger, easier-to-reach control surface for both slide releases and takedown procedures.
The Nitron-finished slide sports front and rear cocking serrations for positive traction during press-checks or slide racking. Steel dovetail front and rear sights provide a traditional 3-dot sight picture that’s easy to acquire in varied lighting.
Internally, the 4.7" carbon-steel barrel wears a nitride finish for corrosion resistance and a long service life. Coupled with the clean, crisp striker-fired trigger of the P320 series, this setup delivers reliable accuracy and fast follow-up shots.
All four included 17-round steel magazines are factory SIG units; one carries a Strike Industries extender, boosting capacity and furnishing a flared base for surer seating.
