Overview

The SIG Sauer P365 12-round magazine adds two rounds over the flush-fit magazine while providing a pinky extension for improved grip. The modest extension adds comfort without significantly compromising concealment, making it a popular choice for shooters who want a full grip on their P365.

The same steel construction and anti-friction coating from the 10-round magazine ensures identical reliability, with the extended base plate adding a comfortable pinky rest. Many P365 owners carry the flush-fit magazine in the gun and a 12-round as a reload for the extra capacity and grip surface.

This capacity represents the sweet spot for many P365 carriers - meaningful capacity increase with improved ergonomics while maintaining practical concealment for everyday carry.

Key Features

  • 12-round capacity for 9x19mm Parabellum
  • Pinky extension for improved grip

  • Compatible with all P365 variants
