Smith & Wesson M&P FPC | 9mm | 16.25″ | MFG#12575

The Smith & Wesson M&P FPC is a folding, optics-ready 9mm carbine designed for compact transport and use with Smith & Wesson double-stack M&P pistol magazines. It ships with one 17-round and two 23-round magazines and features a 16.25″ steel barrel with 1/2-28 threading. For a practical optic under $1,000 that pairs well with a pistol-caliber carbine, consider a Vortex SPARC AR red dot for fast target acquisition on close-to-mid-range engagements.

Typical applications for this platform include range training and PCC competition, and compact transport/storage where a folding carbine is desirable.
