Design and Features

The SIG SAUER P320 M18 uses the proven striker-fired P320 action and SIG’s modular fire control unit, giving users flexibility across frames and slides in the P320 family. The factory optic-ready slide simplifies modern red dot integration without custom machining. The 4″ barrel delivers a balance between sight radius and concealability—ideal for both range sessions and defensive carry.

Ergonomics and Controls

Textured polymer grip frame and thoughtfully placed controls make the M18 comfortable for a wide range of hand sizes. The balance and recoil characteristics reflect the P320 lineage, offering consistent follow-up shots in 9mm with manageable muzzle flip.

Tactical Applications and Caliber

Chambered in 9mm, the M18 provides economical range time and modern defensive terminal performance when paired with quality defensive ammunition. The 9mm round benefits from reduced recoil, higher magazine capacity, and broad aftermarket support—advantages that complement the M18’s role as a service-style compact pistol.

Condition and Value

This listing is for a used pistol showing normal handling wear but no functional issues. The package includes the pistol only, which makes it a straightforward option for buyers who already own optics or accessories. Priced at $495.99, it represents an accessible entry point into a military-derived platform without paying for factory-new premiums.

Buying Considerations

Assess whether you need optics and which footprint fits your preferred red dot; the factory optic-ready slide is a major convenience. Remember that this listing is pistol-only—factor in the cost of sights, plates, or a red dot if required. For shooters wanting a proven, service-derived platform in a compact package, the SIG SAUER P320 M18 is a compelling choice. Shop this product
