Smith & Wesson M&P FPC 9mm Folding Carbine

The Smith & Wesson M&P FPC  is a compact, folding 9mm carbine designed to blend patrol-ready capacity with a small folded footprint for transport and storage. Built around a 16.25″ barrel and an optics-ready receiver, the FPC accepts double-stack M&P pistol magazines and includes on-board storage for magazines and accessories — making it a practical choice for duty, home defense, or range use.

Why buyers choose the M&P FPC

• Folding 16.25″ carbine length that compacts for transport while maintaining rifle performance.

• High capacity: 23+1 rounds standard (compatible with M&P double-stack mags).

• Optics-ready slide/receiver for micro red-dots and modern sighting systems.

• Threaded 1/2-28 muzzle (thread protector included) for muzzle devices or suppressor-ready adapters.

• Durable aluminum receiver and M-LOK style handguard for accessory mounting and modular builds.

• Includes multiple magazines and a carrying solution for immediate use out of the box.

This design balances concealability and capability: long enough to deliver stable, accurate performance yet foldable to a compact chassis for storage and maneuvering. It’s tailored for shooters who want a high-capacity 9mm platform with modern, modular features.
