Modern self-defense and duty pistols demand modularity, predictable ergonomics, and optics-ready performance. Operators and civilian shooters alike want a platform that accepts upgrades, offers fast sight acquisition, and arrives ready to work out of the box.

SIG SAUER P320 is offered here as a Certified Used example that packs practical upgrades: three 10‑round magazines, the original case and owner’s manual, a Gas Pedal magwell, a fiber optic front sight, a ported slide, the OEM trigger and grip module, and a Sig Romeo1 red dot optic. This Certified Used firearm is priced at $788.49 and carries the Certified Used stamp, meaning the pistol is inspected to very good to excellent condition and includes a no‑questions‑asked return policy.

Key features and tactical advantages

The supplied Sig Romeo1 red dot optic significantly reduces target acquisition time compared with iron sights alone, and the fiber optic front sight gives a bright, usable reference should the dot be off or inoperative. A ported slide helps control muzzle rise and can cut follow‑up shot time, especially for shooters managing recoil. The Gas Pedal magwell smooths reloads under stress and pairs well with the three included 10‑round magazines for training or duty routines.

Fit, ergonomics, and platform versatility

The OEM trigger and grip module retain the P320’s modular ethos: adjustability for hand size and tactical preference. Sig Sauer’s modular design means this configuration can work for a variety of shooters and missions—from defensive home carry to range work—while still allowing future upgrades. The listing notes model variants under the broader Sig Sauer family, which speaks to the platform’s widespread adoption and parts support.
