Sig Sauer P365 10-Round Extended Magazine 9mm Luger Blued Steel

The Sig Sauer MAG365910X extends the P365 micro compact's capacity to 10 rounds while maintaining the pistol's concealable profile. This factory magazine provides reliable feeding and enhanced grip surface for improved control during rapid fire sequences.

What Makes This Different

The extended baseplate adds approximately 0.75 inches to overall grip length, creating space for a full three-finger grip without compromising concealability. Factory specifications ensure consistent feeding geometry and spring tension calibrated specifically for the P365 platform. The blued steel construction resists corrosion while maintaining the dimensional tolerances required for reliable function in defensive situations.

Key Features

• Factory 10-round capacity increases firepower by 43% over standard magazines
• Extended baseplate provides full three-finger grip for enhanced control
• Blued steel body with heat-treated spring maintains consistent tension

Field testing demonstrates reliable feeding across various 9mm Luger loads from 115-grain FMJ to 147-grain hollow points. The extended grip surface reduces muzzle flip during rapid strings, improving follow-up shot accuracy in competitive and defensive scenarios. Stainless steel construction maintains spring tension through thousands of loading cycles without degradation.
