Smith & Wesson Model 637 Airweight .38 Special +P 5-Shot Revolver

The Smith & Wesson Model 637 Airweight delivers reliable concealed carry performance in an ultra-lightweight package that won't weigh down daily carry. This 5-shot revolver combines the proven .38 Special +P chambering with advanced aluminum alloy construction for maximum portability without sacrificing stopping power.

What Makes This Different

The Model 637's aluminum alloy J-frame construction reduces overall weight to just 15 ounces while maintaining the structural integrity needed for +P ammunition. Unlike heavier steel-frame alternatives, this revolver provides the same reliable double-action performance in a package that disappears in ankle holsters or pocket carry. The stainless steel barrel and cylinder resist corrosion while handling the increased pressures of +P loads that deliver 20% more energy than standard .38 Special ammunition.

Key Features

• Lightweight aluminum alloy J-frame weighs only 15 ounces for comfortable all-day carry
• Stainless steel 1.875-inch barrel and cylinder rated for .38 Special +P ammunition
• 5-shot cylinder capacity with reliable double-action/single-action trigger system
• Integral front sight provides snag-free draw from concealment
• Matte silver finish reduces glare and resists fingerprints
• Internal lock system provides additional safety when storing
• Compatible with standard J-frame holsters and speedloaders

The 1.875-inch barrel length balances concealability with practical accuracy for defensive distances up to 25 yards. Law enforcement backup gun requirements and civilian concealed carry applications both benefit from the consistent ignition system that functions reliably in adverse conditions. The exposed hammer allows single-action precision shots when needed while maintaining fast double-action capability for defensive situations.
