Smith & Wesson M&P340 – Ultra-Lightweight Magnum Power in a Concealable Revolver

The Smith & Wesson M&P340 is a purpose-built ultra-lightweight revolver designed for deep concealment and dependable defensive performance, combining powerful chambering with a compact, snag-free design.

Chambered in .357 Magnum and compatible with .38 Special, this revolver offers flexibility between high-powered defensive loads and more manageable shooting options. With a 5-round capacity, it maintains the simplicity and reliability that revolvers are known for.

At just 13.8 oz., the M&P340 is exceptionally lightweight, thanks to its Scandium alloy frame, making it ideal for pocket carry, ankle carry, or as a backup firearm. Its 1 7/8" barrel and 6.31" overall length keep the profile compact and easy to conceal.

The double-action-only (DAO) trigger paired with an enclosed hammer ensures a smooth, consistent pull and a snag-free draw—perfect for defensive scenarios. It features a highly visible XS 24/7 tritium night sight, providing fast target acquisition in low-light conditions.

Finished in matte black with black synthetic grips, the M&P340 delivers a clean, functional look while maintaining a secure grip under recoil.
