What's Included
- Smith & Wesson M&P 340 revolver
The M&P 340 uses a scandium-alloy frame finished in matte black to keep weight to about 13.3 oz while maintaining strength. Its stainless-steel cylinder wears a matching black finish, and the fluted cylinder with a knurled ejector-rod tip underscores its compact, carry-ready design.
This model follows the J-Frame Centennial pattern with an enclosed (internal) hammer and double-action-only operation. The two-piece barrel features a stainless steel liner inside an alloy shroud, measuring a nominal 1.875 inches for discreet carry and fast handling.
Chambered for .357 Magnum, the revolver is also compatible with .38 Special +P, offering flexibility across common defensive loads. Capacity is 5 rounds, and an internal lock is included among its safety features.
Sights are fixed, with a pinned ramp front sight that includes a white-dot insert and an integral rear groove on the top strap. Black rubber boot-style grips with gold-colored medallions provide a compact profile and secure hold.
Factory details include model marking "M&P 340" in the yoke cut, the M&P logo, and the circular Military & Police crest. Overall length is approximately 6.31 inches, and the revolver is made in the USA.
