SIG SAUER P320-SPECTRE COMP RXP

Overview: Why this certified used pistol stands out

The SIG SAUER P320-SPECTRE COMP RXP arrives as a solid package for shooters who want immediate capability out of the box. This offering includes three 21-round magazines and the original case, and it’s factory-equipped with a Sig Romeo 1 Pro red dot optic. Being a Certified Used firearm means the pistol has been inspected and graded to a very good to excellent standard and backed by a ‘no questions asked’ return policy—important assurances for buyers who want value without compromise.

What’s in the box

This specific package is purpose-built for immediate use: the pistol, three factory 21-round magazines, an original case, and a mounted Sig Romeo 1 Pro red dot. That combination covers the essentials for range time, training and practical deployment. The triple-mag setup keeps reloads minimal between drills and delivers a competitive advantage during extended sessions.

Three 21-round magazines — practical advantages

Large-capacity magazines are useful for training, competition-style drills, and defensive scenarios where time and follow-through matter. The 21-round count provides a balance between capacity and ergonomics; you maintain reasonable grip clearance while gaining more rounds than standard 15–17 round magazines. For many shooters, fewer magazine changes means better rhythm and fewer transitional errors.

Sig Romeo 1 Pro — efficient red dot integration

The included Sig Romeo 1 Pro red dot optic is a dependable, no-nonsense sighting solution. Red dot optics on pistols speed target acquisition and allow shooters to keep both eyes open, improving situational awareness. The RXP package arrives with the optic pre-installed and zeroed to factory tolerance, so you’re not wrestling with mounts or adapters when you walk into the first live-fire session. If you want the quick route to reflex-optic performance, this pistol delivers it out of the case. View product details and pricing on the shop page.

Certified Used program: what to expect

Buying certified used should reduce risk and increase confidence. This pistol is sold as Certified Used, meaning each firearm has been evaluated and graded as very good to excellent condition. The program also carries a ‘no questions asked’ return policy, which is a straightforward way to mitigate buyer’s remorse or address unexpected issues. For budget-conscious buyers, the advertised price of $1,139.99 represents value—especially when you factor in the included optic, three magazines, and original case.

Ergonomics and handling for real-world use

The P320 platform is known for its modularity and predictable trigger feel when properly set up. The Spectre Comp variant emphasizes controllability and rapid follow-up shots, aided by the compensator-style slide profile and the red dot sight for faster sight acquisition. Whether you’re running timed drills on the range or building defensive skill sets, this pistol’s layout and setup help reduce recoil anticipation and speed accurate follow-ups.

Training recommendations

Start with fundamentals: draw, presentation, and trigger control with the red dot. Use the three magazines to run extended strings and plate drills without constant stops to reload. Pay attention to grip consistency and sight alignment under an optic—small adjustments in hold will translate to quick improvements on the target. Treat the pistol like any precision tool: regular maintenance, ammunition testing, and dry-fire practice will keep it performing well.

Who should consider the SIG SAUER P320-SPECTRE COMP RXP

This package is attractive to competitive shooters stepping into production-style divisions, defensive-minded civilians who want an optic-ready semi-auto, and tactical trainers who value immediate capability for classroom-to-range transitions. Buyers who want a pistol ready to shoot with minimal aftermarket work will appreciate the factory-installed Romeo 1 Pro and the included magazines. Keep in mind that this model is listed in the Semi Auto category and the seller shows it at $1,139.99.

Buying considerations and final notes

When purchasing a certified used firearm, inspect the serial numbers, verify the return policy, and confirm that the optic and magazines are included as described. The Sig Sauer name carries weight for a reason—reputation for engineering, parts availability, and a wide accessory ecosystem. If you value immediate out-of-the-box capability and a generous magazine complement, the P320-Spectre Comp RXP is a compelling option at the listed price.
