Smith & Wesson Model 640 357 Mag 38 Special 5-Shot 2.125" Revolver

The Smith & Wesson Model 640 delivers reliable double-action performance in a compact stainless steel package built for concealed carry and backup duty applications. This J-frame revolver chambers both .357 Magnum and .38 Special +P cartridges, providing versatility for various shooting scenarios.

What Makes This Different

The enclosed hammer design eliminates snag points during draws from concealment while maintaining the reliability of a traditional revolver action. Unlike external hammer models, the Model 640's hammerless configuration allows smooth extraction from pockets or tight holsters. The satin stainless steel construction resists corrosion better than blued finishes, requiring minimal maintenance in harsh conditions.

Key Features

• Dual caliber capability - fires .357 Magnum and .38 Special +P ammunition
• 2.125-inch stainless steel barrel with fixed sights
• Enclosed hammer prevents snagging during concealed carry
• 5-round cylinder capacity with swing-out design for quick reloading
• Satin stainless steel finish resists corrosion and wear
• Internal lock system for additional security
• Compatible with standard J-frame holsters and accessories

The Model 640 performs consistently across temperature extremes and moisture conditions where semi-automatic pistols might experience feeding issues. Law enforcement agencies specify this model for backup duty because revolvers function reliably after extended periods without maintenance. The .357 Magnum capability provides serious stopping power when needed, while .38 Special loads offer reduced recoil for training and practice sessions.
