Today we’re digging into the Smith & Wesson M&P FPC — a 9mm folding carbine that’s shaking up the pistol-caliber world with smart design, portability, and familiar reliability.

Main Themes:
The Big Story — Folding for Convenience.
The FPC folds horizontally to about 16.5 inches, making it extremely easy to store, transport, and carry discreetly.
As Hickok45 put it: "It doesn’t scream gun — it just looks like a random bag."
It’s not just about saving six inches compared to something like a Ruger LC Carbine — it’s about how much easier it is to pack and deploy.

Magazine Compatibility and Storage.
The FPC takes M&P pistol mags, shipping with a 17-rounder and two 23-round mags in many configurations.
The built-in mag storage in the stock is clever — but it’s also one of the more controversial features.

• Some say the mag release is awkward.

• Others love the extra onboard capacity.

And yeah, some folks wish it had been Glock mag compatible — but for M&P owners, it's a huge win.

Build and Construction — Mostly Solid.
The FPC feels solid and well-built, despite using a lot of polymer to keep weight down (~5.78 pounds unloaded).

• Aluminum receiver ✅

• Polymer handguard with M-LOK slots ✅

• Solid M&P 2.0-style grip ✅

However, some reviewers worry about the polymer rail and handguard durability, especially under rough use.

Features You’ll Appreciate.

• Threaded barrel (1/2x28) for suppressors or comps.

• Nice trigger — comparable to an M&P pistol.

• Rear-mounted charging handle — though not everyone loves the feel.

• Optics-ready with a full top rail.

• No iron sights included — plan to add your own.

Reliability and Accuracy.
Generally, the FPC has been very reliable.

• TFB TV: "Half a case of 9mm — zero issues."

• Sub-1-inch groups at 50 yards with good ammo.

• 10/10 hits at 100 yards on silhouette targets.

However, some users report ammo sensitivity — especially light primer strikes with +P or hard-primer ammo like Underwood. Testing your preferred rounds is a smart move.

Potential Negatives:

• Slide/Bolt lock is stiff and awkward — not AR-style.

• Handguard touches barrel in some cases — could affect precision.

• Magazine storage release isn’t very intuitive.

• Charging handle is serviceable but not ideal for everyone.

Comparison — FPC vs Kel-Tec Sub 2000.
Both are folding 9mm carbines, but the FPC edges out in:

• Trigger quality

• Fit and finish

• Ability to mount optics that stay zeroed while folded

If you own an M&P pistol? The FPC is an easy choice.
If you have Glock mags? Maybe stick with the Sub 2000.

Pricing and Value.
At $650-$700 MSRP, the FPC is competitive and well-priced for what you get.
Lightweight, compact, solid shooting — with some ergonomic quirks to be aware of.

Bottom Line:
The Smith & Wesson M&P FPC is a smart, practical folding carbine that blends storage convenience with solid 9mm performance.
It’s not perfect — but if portability, magazine compatibility, and discreet carry matter to you, it’s absolutely worth a look.
