The Smith & Wesson M&P FPC is a compact, semi-automatic .40 S&W carbine built on the same ergonomic platform that made S&W's M&P handguns trusted by shooters everywhere. If you want a pistol-caliber rifle that's genuinely portable—one that folds down to fit tight spaces and deploys fast when you need it—the FPC delivers a familiar grip, proven reliability, and the modularity to suit your setup. It's a no-nonsense option for home defense, vehicle storage, or anyone who values a slim rifle that doesn't demand a lot of real estate.
The FPC's blend of compact design and serious capability starts with a 16.25-inch 4140 steel barrel with 1:10 twist rifling, threaded for suppressors or muzzle devices. The gun runs on simple blowback operation, which means fewer moving parts and straightforward maintenance. Its aluminum receiver is hard-coat anodized, and the bolt carrier is stainless steel—built to handle duty-grade use without fuss. Unfold it and you've got a 30.75-inch platform; fold the polymer stock and it shrinks to just 16.625 inches, making it genuinely stashable in a truck, safe, or closet.
Magazine compatibility is a big practical win: the FPC feeds from standard Smith & Wesson .40 S&W full-size and compact magazines, so if you already own M&P pistols, you've got a supply chain. Both 15-round and 20-round magazines are available, and the carbine has onboard magazine storage built into the frame. The handguard features M-LOK slots across its length plus a Picatinny rail on top, giving you room to mount lights, lasers, or optics exactly where you want them. The gun ships optics-ready with no iron sights—you're free to run whatever sight system fits your mission. Swap grip ergonomics with four interchangeable palm-swell inserts to dial in your hold.
Unloaded weight sits at 5.03 pounds, and it climbs only slightly when you load magazines. This is a rifle that won't exhaust you during extended carry or transport, yet it's substantial enough to shoot straight. Simple, reliable, and built to work.
