Description
Picture this: you’re packing for a range day or a training class, and you want a rifle that doesn’t eat up your entire trunk. You grab your pistol bag, your ammo can, and then you remember the rifle. Or do you? The SMITH & WESSON FPC is the answer to that puzzle—a 9mm carbine that folds in half and fits right in a backpack. I’ve put a few hundred rounds of mixed brass and steel case through one, and it’s a genuinely clever piece of kit that solves a real problem for the practical shooter.
So, what is the SMITH & WESSON FPC? It’s a compact, folding, 9mm carbine designed from the ground up to pair with your existing M&P pistol. It uses the same double-stack magazines, folds horizontally to a mere 16 3/8 inches for easy transport, and comes ready for an optic. At its core, it’s a truck gun, a backpack gun, or a home defense tool that prioritizes convenience without sacrificing function.
Let’s talk about the folding mechanism because that’s the headline act. The horizontal fold is robust, with a positive locking latch that clicks into place when unfolded. There’s no wobble. It feels solid on the shoulder. The genius part is the in-stock magazine storage with a quick-release tab. You can keep a spare 23-rounder right in the buttstock, which means a reload is literally at your fingertips. No fumbling in pockets. That’s smart design. The whole package, with its 16.25-inch barrel, unfolds to a very manageable 30 3/8 inches overall, making it quick to get on target.
Shooting it is where the FPC really shines. The integrated recoil buffer system soaks up what little 9mm carbine recoil there is, making follow-up shots stupidly fast. The flat-face trigger is a pleasant surprise for a factory offering—it’s clean with a crisp break. And because it’s compatible with M&P full-size and compact pistol magazines, your existing kit doubles your ammo capacity. You’re not buying into a new, proprietary magazine ecosystem. That said, the inclusion of one 17-round and two 23-round mags out of the box means you’re ready to roll immediately. The 1/2-28 threaded muzzle is ready for a compensator or suppressor, and the optics-ready picatinny rail means mounting a red dot is drop-in ready.

Pros & Cons
The pros are clear: the folding design is a game-saver for storage and transport, the magazine commonality with M&P pistols is a huge cost and logistics benefit, and the shooting experience is flat-out fun and effective. The included carrying bag is a nice touch. On the con side, it’s a dedicated 9mm platform, so if you’re an AR-15 purist, it’s a different manual of arms. The stock irons are basic, but that’s why the optic cut is there. And at a price of $539.10, it sits in a very competitive spot for what you get.
Who is this for? This is the perfect carbine for the M&P pistol owner who wants a trunk-ready rifle that shares mags and ammo. It’s for the shooter who values a compact footprint for vehicle or home storage without giving up a usable barrel length. It’s also a fantastic option for a new shooter looking for a low-recoil, versatile rifle that’s easy to handle and incredibly convenient to take anywhere. It ships to Missouri and compliant US states, making it accessible for most buyers looking for a practical, modern PCC.
Frequently Asked Questions
Q: Does it really fold with a magazine inserted?
A: Yes, it does. The folding mechanism clears the magazine well, so you can fold and store it with a mag in place, loaded or unloaded. The latch system is robust and locks securely both folded and unfolded.
Q: Will it work with my M&P Shield Plus magazines?
A: No. The FPC is compatible with M&P double-stack magazines, like those from the full-size M&P 9 2.0 or the M&P Compact. The single-stack Shield magazines are not compatible.
Q: Is the thread protector removable for a muzzle device?
A: Absolutely. The 1/2-28 threaded muzzle comes with a simple thread protector that screws off easily, allowing you to install a flash hider, compensator, or direct-thread suppressor mount. Remember, an FFL transfer is required for firearm purchases before you can take possession.
