Pkmyr Mag Sleeve M&p 9c To M&p 9

The Pachmayr Mag Sleeve for M&P 9C to M&P 9 is a magazine adapter that extends the capacity and grip ergonomics of compact pistols by allowing full-size magazines to function reliably in subcompact frames. This proven accessory bridges the gap between concealment-optimized carry guns and duty-ready capacity, giving operators the flexibility to adjust their loadout based on the tactical situation at hand.

The sleeve slides securely over standard M&P 9 full-size magazines, creating a stable interface with the M&P 9C compact frame while adding measurable grip circumference. This increases both round count and control during rapid fire sequences without requiring a complete magazine swap system. The design is passive—no springs, levers, or secondary mechanisms—meaning installation is field-reversible and maintenance-free. Dimensions of 2.76 x 1.4 x 4.25 inches and a weight of 0.06 lbs ensure minimal footprint and zero impact on carry weight distribution.

This adapter is purpose-built for operators who rotate between concealed-carry M&P 9C configurations and duty or range training with full-size platforms. Law enforcement and civilian shooters commonly employ magazine sleeves during transitions from plainclothes to duty uniform, or when training across multiple pistol variants within the same platform. The M&P 9C to M&P 9 compatibility is particularly valuable given the M&P's prevalence in both government and commercial markets, ensuring straightforward magazine compatibility and no exotic components.
