The Smith & Wesson has expanded the M&P FPC (Folding Pistol Caliber Carbine) line with a new model chambered in 10mm Auto, building upon the established platform previously available in 9mm Luger and .40 S&W. This expansion reflects a growing interest in the 10mm cartridge, known for its increased power and flatter trajectory compared to other pistol calibers. The FPC series, in general, is designed for portability and ease of storage, addressing a market niche looking for compact yet capable firearms.

The 10mm FPC features a 16.25-inch threaded barrel, which is crucial for maximizing the ballistic potential of the 10mm cartridge. The 9/16x24 TPI threading allows for the attachment of various muzzle devices, including suppressors, catering to users who prioritize noise reduction or recoil management. The blowback operating system, contained within an aluminum tube receiver, contributes to the carbine's overall durability and simplicity. This design is common in pistol-caliber carbines, prioritizing reliability and ease of maintenance.

As always, ergonomics play a factor in the 10mm FPC's design. The grip and trigger are derived from Smith & Wesson's M&P "Big Ten" series of handguns, providing a consistent feel for users familiar with those platforms. Interchangeable backstraps and a flat-faced trigger further enhance user comfort and control, reflecting a trend in modern firearm design towards greater customization and improved ergonomics.

The carbine's adaptability is enhanced by a full-length Picatinny rail along the handguard and M-Lok slots for accessory mounting. This allows users to customize the firearm with optics, lights, lasers, and other accessories, making it suitable for various applications, including recreational shooting, home defense, and even some hunting scenarios. The absence of included iron sights provides the user with the flexibility to select their preferred sighting system.

A key feature of the 10mm FPC is its integrated two-stage recoil buffer system, designed to mitigate the increased recoil associated with the powerful 10mm cartridge. This system aims to provide a more comfortable and manageable shooting experience, a critical consideration for a blowback-operated carbine in this caliber. The carbine's weight of 5.89 pounds also contributes to stability and recoil absorption.

The 10mm FPC folds to an overall length of 16.5 inches makes it portable firearm, facilitating easy storage and transport. The integrated magazine carrier within the stock, capable of holding two spare magazines in addition to the one in the action, enhances the carbine's practicality by providing readily available ammunition. This feature is particularly useful in situations where rapid reloading is essential.

Smith & Wesson has positioned the 10mm FPC competitively within the market, with an MSRP of $699. The package includes three 15-round magazines, with a 10-round magazine version available for regions with capacity restrictions. A discreet carrying case is included, providing a convenient means of transporting the carbine and its accessories. This pricing and accessory package aim to provide value to the consumer.

The introduction of the 10mm FPC demonstrates Smith & Wesson's responsiveness to market trends and consumer demand. The 10mm cartridge's resurgence in popularity, driven by its performance characteristics, has created a demand for firearms that can effectively use its capabilities. The FPC platform, with its folding design and modularity, provides a unique solution for this demand.

Overall, the Smith & Wesson M&P FPC in 10mm Auto offers a blend of power, portability, and adaptability. Its design, incorporating features like a recoil buffer system, integrated magazine storage, and modular accessory mounting, positions it as a versatile firearm suitable for a range of applications. The competitive pricing and included accessories further enhance its appeal to firearm enthusiasts.
