Strike Industries P320MMR Modular Magazine Release - Sig P320 Black

The Strike Industries P320MMR Modular Magazine Release transforms the standard Sig P320 magazine release with enhanced ergonomics and faster reload capabilities. This precision-machined component addresses the common complaint of the factory release being too small and difficult to manipulate under stress.

What Makes This Different

Unlike the factory polymer release, the P320MMR features an enlarged paddle design that provides 40% more surface area for positive engagement. The modular construction allows shooters to configure the release for ambidextrous operation or optimize it for their specific grip style. CNC-machined from 17-4 stainless steel with a black nitride finish, this upgrade delivers consistent performance where polymer components often flex or wear.

Key Features

• Enlarged paddle design with 40% more surface area than factory release
• 17-4 stainless steel construction with black nitride finish for corrosion resistance
• Modular design allows ambidextrous configuration or single-side optimization
• Direct drop-in replacement for all Sig P320 variants including full-size, carry, and compact
• Precision CNC machining ensures consistent engagement with minimal side-to-side play
• Low-profile design prevents snagging on holsters or gear
• Tool-free installation with factory springs and hardware

Competition shooters report faster reload times due to the positive tactile feedback and enlarged activation surface. The enhanced ergonomics prove particularly beneficial during high round count training sessions where hand fatigue can compromise manipulation of smaller controls. Law enforcement and military users appreciate the reliability under adverse conditions, as the steel construction resists impact damage that can disable polymer releases.
