Smith & Wesson M&P FPC 9mm Folding Pistol-Caliber Carbine with SIG Romeo5 Red-Dot, Threaded Barrel & Magazine-Storing Stock
The M&P FPC is Smith & Wesson’s first side-folding pistol-caliber carbine, introduced in 2023. Built around a straight-blowback 9mm action, it folds to only 16.4 inches without disturbing the mounted optic, making it highly portable while preserving zero. This example remains in very good condition, comes outfitted with a factory-installed SIG Sauer Romeo5 red-dot, and ships with four magazines and its original soft case.

Details
The left-folding design hinges behind the receiver, reducing overall length to 16.4 inches for discreet transport. Because the barrel and receiver remain aligned, the SIG Romeo5 stays mounted and zeroed when the carbine is opened or folded.
The polymer stock incorporates spring-loaded compartments that secure two spare double-stack M&P9 magazines, keeping 46 ready rounds on board before you add the magazine in the well. A QD socket is built into the stock for one-point sling attachment.
The 16.25-inch 4140 steel barrel features dual 1/2-28 threads with a tri-lug adapter, supporting common muzzle devices or suppressors. A 1:10 twist stabilizes a wide range of 9mm bullet weights, and the free-float polymer M-LOK handguard offers slots for accessories.
S&W fits a flat-face trigger and reversible magazine catch for consistent, ambidextrous control. The aluminum upper receiver, polymer lower, and overall weight of about 5 lb 1 oz keep handling quick for PCC competition or defensive roles.
This package adds practical upgrades out of the box: the Romeo5 red-dot for rapid aiming and a Magpul angled foregrip for improved hand placement, all housed in the factory soft case for convenient carry.
