Take your SIG P320’s ergonomics and functionality to the next level with the Strike Industries Modular Magazine Release — a precision-engineered, user-customizable upgrade built for speed, comfort, and control. Constructed from high-strength materials and finished in sleek matte black, the SI-P320-MMR (P320MMR) gives shooters the flexibility to tailor their mag release to their grip, hand size, and shooting style for ultimate performance and confidence under pressure.
Premium Construction and Design
Machined from aircraft-grade aluminum and coated with a durable black anodized finish, this magazine release offers lightweight strength and corrosion resistance for long-term reliability. The modular design allows for quick, easy customization, letting you swap between included button faces to achieve the perfect reach and texture. Strike Industries’ signature attention to detail ensures every edge is clean, every surface is functional, and every component fits seamlessly with factory SIG Sauer tolerances.
Modular & Customizable for Every Shooter
The Strike Industries Modular Magazine Release includes interchangeable button faces designed for a variety of applications — whether you prefer a low-profile configuration for concealed carry or a larger, more aggressive surface for competition or duty use. The modular setup allows you to easily change button faces with basic tools, ensuring you get the perfect combination of accessibility and comfort.
The textured button surface enhances grip while minimizing slippage, ensuring quick, consistent reloads even under stress or while wearing gloves.
Precision Fit for SIG P320 Pistols
Designed specifically for the SIG Sauer P320 platform, the SI-P320-MMR is compatible with most standard and modular P320 grip modules. It installs seamlessly in place of the factory magazine release and maintains full ambidextrous functionality (when reversed for left-hand operation). Whether you’re upgrading a duty pistol, a carry gun, or a competition setup, the P320MMR delivers enhanced control without compromising reliability.
Enhanced Functionality & Ergonomics
Improved Access: Angled geometry provides faster and more natural thumb engagement without breaking your shooting grip.
Smooth Operation: Precision-machined fit ensures reliable, repeatable magazine ejection every time.
Custom Feel: Interchangeable release buttons let you fine-tune both size and texture to suit your hand.
