Smith & Wesson M&P FPC 16.25″ Threaded Folding Carbine
About this product
The Smith & Wesson M&P FPC 16.25″ threaded folding carbine is a compact semi-auto rifle that breaks down for storage and travel without losing any of the M&P platform reliability you already trust. Built around a 16.25-inch barrel with a 1/2×28 threaded muzzle, this folding carbine stows spare magazines right in the stock and uses M-LOK and Picatinny rails for lights, lasers, or optics. It’s a practical, packable shooter for anyone who wants a full-size caliber in a smaller package.

Key features
- Side-folding stock with integrated magazine storage – Why it matters: you can carry two spare mags directly in the stock, so reloads are fast and you don’t need extra pouches or bags.
- 16.25″ threaded barrel (1/2×28) – Why it matters: you can add a suppressor or muzzle brake without a gunsmith, and the included thread protector keeps the crown safe when running bare.
- Full-length M-LOK and Picatinny top rail – Why it matters: mount a red dot, light, and foregrip exactly where you want them, and the handguard stays slim for a natural grip.
- Tool-free field strip using the grip tool – Why it matters: you can break the gun down for cleaning or service in seconds without a punch or screwdriver—just the tool stored in the grip.
- Familiar M&P ergonomics – Why it matters: if you already shoot an M&P pistol, the grip angle, controls, and manual of arms carry over, so training time is minimal.
Who it’s for
This carbine is for the shooter who wants a packable rifle that still hits like a full-size. It’s a natural fit for truck guns, bug-out bags, or anyone who lives in tight spaces but wants reliable 9mm performance. New gun owners will appreciate the simple controls and easy maintenance.
Pros and cons
- Pro: Compact folded length makes it easy to stash in a backpack or behind a seat.
- Pro: Uses common M&P 9mm magazines, so you can share mags with your pistol.
- Con: The side-folding stock adds a little width when folded—not an issue for most bags, but worth noting if you’re packing in a slim case.

FAQ
Can I mount a suppressor on the Smith & Wesson M&P FPC?
Yes. The barrel is threaded 1/2×28 and comes with a thread protector. Just make sure your suppressor is rated for 9mm and the barrel shoulder is clean before mounting.
What magazines does the M&P FPC use?
It ships with one 23-round M&P 9mm magazine, and it accepts all standard M&P 9mm double-stack magazines. That includes 17-round, 23-round, and extended options.
Is the M&P FPC legal in my state?
Because it has a 16.25″ barrel and a stock (not a brace), it’s classified as a rifle under federal law. Check your local laws—some states restrict folding stocks or magazine capacity. We ship to all 50 states, but you are responsible for compliance.
How do I clean the M&P FPC?
Field strip using the grip tool: remove the takedown pin, lift the upper, and pull the bolt. Clean the barrel and bolt with standard gun solvent, then lightly oil. Reassemble in reverse.
