Mag Act-mag S&w M&p 9mm 17rd Blue

The Armscor Mag Act-Mag S&W M&P 9mm 17-Round Blue magazine is a purpose-built duty and training magazine engineered to OEM specifications for the Smith & Wesson M&P full-size platform. This aftermarket magazine delivers the same dimensional tolerances and performance standards as original equipment while leveraging high-grade steel construction and polymer components for reliability across extended service life and high-round-count environments.

Built with a steel magazine body and polymer base plate, the 17-round capacity provides a full-size grip magazine profile suited for duty carry and range operations. The flush-fit design maintains the ergonomic geometry of the M&P handgun without protrusion, preserving holster compatibility and retention characteristics critical to tactical deployments. Armscor's manufacturing precision ensures consistent feed reliability and smooth insertion into the magazine well without play or looseness—essential factors for time-critical training or field scenarios.

This magazine serves law enforcement officers, military personnel, armed security professionals, and civilian trainers who require genuine-specification M&P magazine capacity for qualification courses, defensive firearms instruction, or operational readiness. The 9mm platform's controllability and ammunition availability make 17-round magazines essential for realistic training progressions and duty applications. Armscor Act-Mag products have earned adoption by agencies valuing OEM-compatible aftermarket alternatives that reduce magazine inventory costs without compromising fit or function.

The M&P platform remains the standard-issue handgun for federal and state law enforcement agencies and continues as the primary training platform for concealed-carry certification courses nationwide. Magazine reliability directly impacts training outcomes and operational readiness, making OEM-spec replacements and duty backups fundamental to any M&P user's accessory collection.
