The Smith & Wesson M&P FPC 5.7x28mm Folding Pistol Carbine (Model 14170) is a highly innovative and compact folding carbine chambered in the high-velocity 5.7x28mm cartridge. Designed for shooters in states with magazine capacity restrictions, this version of the M&P FPC comes with three 10-round magazines while maintaining all the advanced features that make the platform stand out. With a 16.25-inch threaded barrel and an M-LOK compatible handguard, the Model 14170 delivers excellent performance in a package that folds for easy transport and storage.
Compact Folding Design with Full Performance
The M&P FPC features a unique folding mechanism that allows the carbine to collapse in half, dramatically reducing its overall length when not in use. This makes it ideal for storage in vehicles, backpacks, or safes where space is limited. Despite its compact folded size, the carbine retains a full 16.25-inch barrel that maximizes the ballistic potential of the 5.7x28mm cartridge. The threaded barrel allows users to easily attach suppressors, muzzle brakes, or flash hiders, providing added versatility for both recreational and defensive applications.
The 5.7x28mm caliber offers a unique combination of high velocity, flat trajectory, and very low recoil. Originally developed for personal defense weapons, this cartridge provides excellent terminal performance while remaining comfortable to shoot during extended range sessions. The M-LOK rail system offers ample mounting space for optics, lights, lasers, and other accessories.
