When a sidearm needs to disappear under a cover garment yet run like a duty pistol, I want a platform that’s proven, modular, and ready for glass out of the box. Reliability matters, and so does the ability to build the gun around the mission—whether that’s daily carry, range work, or home defense. This one checks those boxes with quiet confidence.
SIG SAUER P320
Why this optics-ready compact belongs in your kit
This Certified Used P320 X Compact arrives set up for modern aiming solutions from the jump. Optics-ready slides change the game: faster target acquisition, less time hunting for the front sight, and more attention on threat identification. Pair that with factory night sights and you’ve got a sighting system that handles low light and transitional spaces without drama. It’s a combo that’s earned its place in duty holsters, concealed carry rigs, and training benches across the country.
Two 15-round magazines come standard with this listing, which means you’re not scrambling for spares on day one. Magazine commonality in the P320 family is excellent, and those 15-rounders strike a sweet balance between capacity and concealability in a compact frame. For a Semi Auto in the compact footprint, that’s the right kind of insurance.
Certified Used value without compromise
There’s used, and then there’s Certified Used. This listing is clearly labeled as Certified Used, which means it’s held to a very high standard: very good to excellent condition, backed by a no-questions-asked return policy. That’s not just marketing—it’s peace of mind. You get the original case and owner’s manual, and you can put the savings toward quality ammunition, a holster, and the optic of your choice.
At $512.99, the price lands in a sweet spot for shooters who want professional-grade hardware without paying the brand-new premium. The Certified Used process lets you secure a known performer at a cost that keeps the rest of your loadout on budget.
What the X Compact setup brings to the fight
Optics-ready slide
The slide is cut for a pistol optic, letting you mount a red dot and capitalize on faster presentation, superior tracking, and more precise shot placement at speed. For many shooters, a red dot also reduces eye strain and simplifies alignment under duress.
Factory night sights
Night sights matter when the light isn’t cooperating. Whether you’re navigating a dim hallway or training past dusk, tritium-based sights help you orient the pistol fast while your white light handles target ID.
Two 15-round magazines
Fifteen rounds per mag in a compact grip gives you staying power without compromising concealment. Reloads are clean with the P320’s magwell geometry, and the mags drop free with confidence.
Original case and manual
The original case keeps the pistol protected in transit and storage, and the manual is your reference for safe operation and maintenance. It’s a small thing that speaks to the overall condition and completeness of this Certified Used package.
Built for carry, confident at the range
Sig Sauer engineered the P320 platform around a modular fire control unit and a user-friendly grip angle. The X Compact variant trims weight and bulk while retaining excellent shootability. That translates to controlled recoil, consistent tracking in rapid strings, and no-nonsense handling when stress hits. The Semi Auto category is full of options, but the P320 line has become a benchmark for a reason: it’s simple to run, easy to maintain, and adaptable to your preferences.
Since models and calibers can vary within the P320 family and this listing specifies “Various” for model details, check the product page for current configuration specifics before you mount an optic or order extra barrels. Whatever the configuration, the P320 design is known for its straightforward manual of arms and well-sorted controls.

Carry-ready features that matter day one
Optic-first mindset
A pistol that’s optics-ready from the factory saves you time, money, and guesswork. No need for custom milling or adapter hunts—mount your red dot, confirm torque, zero properly, and move straight into live-fire validation.
Low-light confidence
Night sights complement a handheld or weapon-mounted light, giving you redundant capability if the dot or batteries fail. Good gear is layered; this pistol checks that box.
Holster and support gear compatibility
The P320 ecosystem is broad, so you’ll find holsters, mag pouches, and sight/optic support without a long search. That means you can build a complete, mission-ready setup quickly.
Training notes from the field
Run a 25-yard zero on your red dot if you mount one; it provides a practical blend of near and far holds while keeping the offset manageable. Confirm mechanical zero on irons after optic install. For reliability checks, I like a 200–300 round shakedown across multiple ammunition types. Track ejection pattern, note any anomalies, and log it in your maintenance notebook. The P320 platform tends to run cleanly with a light film of quality lubricant on rails and barrel hood; don’t overdo it.
Practice one-handed manipulations using the optic housing against a firm edge if your optic allows it, but verify mounting security first and follow safe handling protocols at all times. With 15-round magazines, pressure-test your reloads from concealment—clean draws, positive mag seating, firm top rounds. Consistency beats speed until speed arrives naturally.
Who this pistol suits best
If you want a compact Semi Auto that supports modern pistol optics, offers solid capacity, and comes with night sights out of the box, this listing hits the mark. The Certified Used status makes it especially appealing for new shooters assembling a first serious carry setup and seasoned hands looking to add a capable compact without draining the budget. The return policy removes the guesswork so you can focus on capability rather than uncertainty.
