The Smith & Wesson M&P340: Compact Power for Personal Defense
Smith & Wesson's M&P340 represents the pinnacle of small-frame revolver design—a firearm built on decades of proven reliability and refined through countless real-world applications. This is a serious tool for serious purposes.
Construction and Materials
The M&P340 employs a Scandium alloy frame, a material choice that distinguishes it from conventional steel revolvers. Scandium provides exceptional strength while dramatically reducing weight—a critical advantage in a personal defense revolver designed for daily carry. The stainless steel cylinder resists corrosion and maintains reliability across varied conditions.

Why This Revolver Works
The internal hammer design eliminates snag points—a critical feature when drawing from concealment or a holster. The double-action-only trigger provides both safety and consistency. XS Sights tritium night sights ensure target acquisition in low-light conditions without requiring batteries or external light sources.
The .357 Magnum chambering delivers genuine stopping power while maintaining the option to fire milder .38 Special loads for practice or reduced recoil applications.
The J-Frame Legacy
Smith & Wesson's J-Frame platform has earned its reputation through real-world performance. Law enforcement agencies, security professionals, and armed citizens have relied on this design for decades. The M&P340 carries that legacy forward with modern materials and contemporary sighting systems.
This is a revolver for those who understand that simplicity, reliability, and proven design matter more than novelty.
