S&W M&P Shield Plus 9mm 13rd Extended Magazine

The 13-round extended magazine ships with the M&P Shield Plus and is the highest-capacity factory option for the platform. The extended basepad adds a pinky extension that improves grip purchase for medium and large hands, a practical advantage in a single-stack-width carry pistol.

The Shield Plus achieves 13 rounds in a single-stack-width design by using a staggered-stack, short-reset magazine geometry. This mag is NOT cross-compatible with older Shield 1.0 or Shield EZ magazines.
