Smith & Wesson M&P FPC 9mm Folding PCC — 16.25-in Threaded Barrel, 23+1 Capacity, Primary Arms SLx Red-Dot
S&W’s first folding pistol-caliber carbine, the M&P FPC combines 9mm compatibility with M&P double-stack magazines, a side-folding design that locks the optic in place, and a factory-threaded barrel ready for muzzle devices. This example adds a Primary Arms SLx MD-25 red-dot sight, giving the buyer a ready-to-run package that folds to just 16.5 inches for transport.

What’s Included
- Primary Arms SLx MD-25 1× red-dot sight with ACSS CQB reticle, installed on riser mount
- Two 23-round S&W M&P double-stack magazines (steel, extended)
- One 17-round S&W M&P double-stack magazine (steel, flush-fit)
The FPC’s side-folding mechanism is positioned between the grip frame and fore-end, allowing the carbine to fold without disturbing the optic or sight-in. Folded, it measures only 16.5 inches, making it exceptionally compact for storage or transport.
A 16.25-inch 4140 steel barrel is free-floated inside a lightweight 6061-T6 aluminum M-LOK handguard. The muzzle is threaded 1/2-28 UNEF for suppressor or muzzle-device installation, and the 1:10 RH twist stabilizes a wide range of 9mm bullet weights.
The polymer stock folds with the barrel and stores two spare magazines, bringing total on-board capacity to 63 rounds (one 23-rd mag seated, two 23-rd spares, plus one in the chamber). A rubber recoil pad and interchangeable palm-swell grip inserts add user comfort.
Controls are shooter-friendly: an ambidextrous, reversible magazine release, cross-bolt safety, and a charging handle that doubles as the folding latch. A full-length Picatinny top rail offers additional optic or accessory placement beyond the included red-dot.
