Smith & Wesson M&P 340 .357 Mag 5-Shot Scandium J-Frame Revolver

The Smith & Wesson M&P 340 delivers magnum power in an ultralight package that weighs just 11.4 ounces unloaded. This scandium alloy J-frame revolver handles both .357 Magnum and .38 Special +P cartridges with equal reliability. The PVD-coated cylinder and 1.875-inch barrel provide enhanced corrosion resistance for daily carry.

What Makes This Different

The scandium alloy frame construction reduces weight by 30% compared to steel-frame revolvers while maintaining structural integrity under magnum pressures. The PVD (Physical Vapor Deposition) coating on the cylinder creates a harder, more durable surface than traditional bluing. XS Sights 24/7 tritium front sight provides instant target acquisition in low-light conditions without requiring batteries or maintenance.

Key Features

• Scandium alloy frame weighs 40% less than comparable steel revolvers
• Dual caliber capability: .357 Magnum and .38 Special +P ammunition
• PVD-coated cylinder resists wear and corrosion better than standard finishes
• XS Sights tritium front sight glows for 12+ years without replacement
• 1.875-inch barrel optimizes velocity while maintaining concealability
• 5-shot cylinder capacity with smooth double-action trigger
• Black matte finish reduces glare and visible wear patterns

Field testing demonstrates consistent accuracy at defensive distances with both caliber options. The lightweight construction makes extended carry comfortable while the magnum capability provides stopping power when needed. Weather sealing around the cylinder crane and trigger guard protects internal components from moisture and debris. Law enforcement agencies appreciate the reliability under adverse conditions, while civilian carriers value the balance of power and portability.
