Why this SIG SAUER P320 package matters

This listing is more than a bare pistol — it’s a ready-to-shoot system. The gun ships with two 17-round magazines and two 15-round magazines, the original case and owner’s manual, a Foxtrot 2R light, co-witness night sights, and a Romeo1 Pro red dot optic. At a price of $664.99 for a Certified Used firearm, you’re getting substantial value without cutting corners.

Optics and sighting system

The included Romeo1 Pro red dot optic paired with co-witness night sights gives fast target acquisition in daylight and reliable sight alignment after optic failure. For tactical drills and defensive postures, this combination reduces transition time and improves accuracy at common engagement distances.

Lights and low-light capability

The Foxtrot 2R weapon light adds immediate target identification and positive target engagement in low-light scenarios. Integrated with co-witness sights, the light makes dynamic room clearing and low-visibility household defense safer and more controlled.

Magazines, condition and confidence

Two 17-round and two 15-round magazines provide flexibility for range sessions and duty-style reloads. The Certified Used stamp indicates the firearm has been inspected and deemed very good to excellent condition, and all Certified Used guns come with a ‘no questions asked’ return policy — useful peace of mind when buying pre-owned.

Listed in our Revolver category, this SIG SAUER P320 stands out on its own merits as a modular, optics-ready platform backed by Sig Sauer’s reputation. The kit’s completeness—case, manual, dual magazine capacities, optic, light, and night sights—makes it a turnkey option for buyers who want minimal additional purchases.
