Strike Industries P320-MMR Modular Magazine Release

Enhanced Control and Customization

The Modular Magazine Release (MMR) for the Sig Sauer P320 transforms how you interact with your pistol's magazine controls. This innovative design allows you to attach different-sized extensions to the magazine release, giving you the ability to customize reach and ergonomics to match your hand size and shooting style.

Quick-Swap Design

Unlike traditional extended magazine releases that require complete disassembly to change, the MMR features a hot-swap system. You can quickly interchange extensions in the field to suit your needs without taking apart the entire assembly. This flexibility means one release works for multiple shooters or adapts as your preferences evolve.

Robust Construction

• Material: Stainless steel with QPQ black finish
• Installation: Lightweight drop-in design—no gunsmithing required
• Durability: Professional-grade finish resists corrosion and wear

Why This Matters

The P320 is an excellent platform, but its standard magazine release can be difficult to reach for shooters with larger hands or those wearing gloves. The MMR solves this problem while maintaining the reliability and simplicity you expect from your defensive or competition pistol. The modular approach means you're not locked into one configuration—adapt it as your needs change.
