SIG SAUER P320 M18

Overview

This Certified Used SIG SAUER P320 M18 is optic-ready and includes an ambidextrous safety and Sig H3 front and rear night sights — features that matter when you need fast, repeatable sight acquisition. The Certified Used designation signals the firearm is held to a high-quality standard and comes with a simple, ‘no questions asked’ return policy.

Key Features

Optic-Ready Slide

The optic-ready slide allows installation of a compact red dot for quicker target acquisition without extensive gunsmithing. For personal security or duty, an optic shortens sight radius advantageously in low-light scenarios.

Controls and Sights

The ambidextrous safety offers positive, accessible manual control for left- and right-handed shooters. SIG’s H3 tritium night sights provide a bright, low-light sight picture for engagements when ambient light is limited.

Included Gear

Each purchase includes the owner’s manual and two magazines — one 17-round and one 21-round — giving you immediate capacity and flexibility for range work and carry rotations. At a price of $474.99 for a Certified Used example, this model represents a practical balance of performance and value. Shop this product
