SIG Sauer P320 Compact .40 S&W Semi-Automatic Pistol – Nitron Slide, Night Sights, 13+1
The P320 Compact in .40 S&W delivers the modular, striker-fired performance that defines SIG’s P320 line, packaged in a now-discontinued caliber and size combination. A stainless steel fire-control unit, Nitron-coated slide, and SIGLITE night sights give this pistol a feature set that appeals to shooters and collectors alike. Its factory holster/2-mag bundle and ambidextrous controls add practical value right out of the box.
Condition
Overall Condition: Very good condition, showing only light, superficial signs of prior handling or use.
Bore Condition: Excellent – clean, mirror finish, no signs of wear.
Rifling Condition: Excellent – sharp lands and grooves.
Specific Condition Notes: The slide and frame display a few scattered scratches and minor blemishes consistent with careful range use, but no deep gouges or structural concerns. The bore remains bright and sharp, reflecting limited round count.
What’s Included
- SIG SAUER factory hard case (black)
- Two 13-round SIG SAUER factory steel magazines marked "Made in Italy"
- SIG SAUER polymer paddle holster (OWB)
- SIG SAUER P320 owner’s manual
This Compact variant houses a 3.9-inch stainless steel barrel inside a Nitron-finished slide with front and rear serrations for confident manipulation. The loaded-chamber inspection port and external extractor contribute to straightforward status checks and reliability.
The serialized fire-control unit is the heart of the P320 system, allowing the user to convert between calibers, slide lengths, and grip modules without additional paperwork—flexibility unique to this platform.
Fully ambidextrous slide-catch levers and a reversible magazine release support right- or left-handed operation. Coupled with a curved trigger and internal striker, the pistol maintains a consistent pull across every shot.
SIGLITE tritium three-dot sights provide clear, low-light targeting, while the integral four-slot MIL-STD-1913 rail accepts lights or lasers for duty or home-defense roles.
As the .40 S&W Compact model is no longer in current production, examples in this condition—with factory case, holster, and dual magazines—are becoming harder to find.
