Smith & Wesson M&P9 FPC 9mm 23rd Magazine

This is the 23 round 9mm magazine Smith & Wesson built for the M&P FPC pistol caliber carbine. It also runs in M&P9 M2.0 pistols, so one set of long mags covers both the carbine and the handgun on your belt.

The body is stainless steel with a corrosion resistant finish. A polymer adapter comes on the magazine to give a flush, consistent fit in the FPC, and the floor plate and adapter come off for cleaning. Inside is a high tensile steel spring and a polymer follower.
