Description
There are folding pistol caliber carbines, and then there is the M&P FPC. Smith & Wesson took a hard look at what people wanted out of a packable 9mm and delivered a carbine that folds sideways at the breech, dropping from 30.375 inches down to 16.375 inches without you having to pull your optic off first. That side-folding design is the detail that matters. Mount a red dot on the full-length Picatinny rail, zero it, fold the gun, throw it in the included carry bag, and your zero stays put when you unfold it at the range.
Why the M&P FPC Makes So Much Sense
If you already run an M&P pistol, this carbine feels like home. The grip is essentially the M&P M2.0 compact pistol grip, complete with interchangeable palmswell inserts to fit your hand, and it feeds from M&P full-size and compact double-stack magazines. Smith & Wesson ships it with one 17-rounder and two 23-round extended mags, and the buttstock has built-in storage that carries both spares right on the gun with a quick-release tab for fast access. That is a lot of 9mm on board without touching a pouch or pocket.
Built for the Range and the Road
The 16.25 inch 4140 steel barrel wears a 1/2×28 threaded muzzle with a protector, so adding a suppressor is a simple twist away, and the straight blowback action with an integrated recoil buffer keeps things soft and smooth. The M-LOK handguard gives you room for a light or hand stop, the flat-face trigger breaks clean, and the whole package weighs right around 5 pounds. Reviewers consistently report tight groups at 25 and 50 yards and trouble-free feeding across a wide range of ammo.
What Comes With the FPC Carbine
Beyond the three magazines, the FPC includes a fitted carry bag with Velcro straps and storage compartments for your mags and the extra grip inserts. It is a genuinely useful case, not a throwaway box. Made in the USA and built the way you would expect from Smith & Wesson.

Frequently Asked Questions
What magazines does the Smith & Wesson M&P FPC use?
The FPC feeds from Smith & Wesson M&P full-size and compact double-stack pistol magazines, so if you already own an M&P 9mm pistol, your mags will work in both guns. It ships with one 17-round and two 23-round magazines, and the buttstock stores both spares on the gun with a quick-release tab.
Can I fold the FPC with an optic mounted?
Yes, and that is one of its biggest advantages over older folding carbines. The FPC folds horizontally to the side, so a red dot or optic on the top Picatinny rail never interferes with the folding mechanism. Users report that zero holds through repeated folding and transport in the bag.
Does the M&P FPC come with sights?
No, it ships optics ready with a bare full-length Picatinny rail up top. Most owners run a red dot since it pairs naturally with the 9mm carbine's practical range, though you can mount backup irons or a low-power optic if you prefer. Plan on picking up a sight when you order.
Is the FPC carbine suppressor ready?
It is. The 16.25 inch barrel is threaded 1/2×28 and comes with a thread protector installed, so most 9mm suppressors will spin right on. The blowback action runs well suppressed, and plenty of owners report it is a great host with both standard and subsonic loads.
