SMITH & WESSON M&P FPC

The FPC was already a clever little carbine. In 10mm, it’s a legitimately good idea. Fold it in half, stash it in the included carry bag, and it disappears into a truck seat. The stock holds two spare mags — you get three total — while the M-LOK forend and top rail take your optic and light, and the 9/16×24 threaded muzzle is ready for a can. Familiar M&P grip and flat-face trigger, only now with a carbine barrel letting 10mm finally do what it always wanted to.

Because 10mm deserved a stock all along.
