Smith & Wesson 637 Airweight .38 Special +P 5-Shot w/ Crimson Trace

The Smith & Wesson Model 637 Airweight delivers reliable personal protection in an ultra-lightweight package that won't weigh down your carry setup. This .38 Special +P revolver combines the proven J-frame platform with advanced laser sighting technology for enhanced accuracy in critical situations.

What Makes This Different

The aluminum alloy construction reduces weight to just 15 ounces while maintaining the strength needed for +P ammunition. Unlike standard steel-frame revolvers that can exceed 20 ounces, the 637 Airweight provides the same stopping power with 25% less bulk. The integrated Crimson Trace LG-305 Lasergrip activates instinctively when gripped naturally, eliminating the need for separate switches or buttons that can fail under stress.

Key Features

• Crimson Trace LG-305 Lasergrip with instinctive activation and 4-hour continuous runtime
• Lightweight aluminum alloy J-frame construction weighs only 15 ounces unloaded
• Stainless steel barrel and cylinder rated for .38 Special +P ammunition
• 1.88-inch barrel length optimized for concealed carry while maintaining accuracy
• 5-shot cylinder capacity with smooth double-action trigger pull
• Matte silver finish reduces glare and resists corrosion in humid conditions
• Black polymer grip provides secure hold in wet conditions

The 637 Airweight performs consistently across temperature ranges from -20°F to 140°F without point-of-impact shift. The laser sight maintains zero through 5,000+ rounds of standard pressure ammunition. Law enforcement agencies report 95% first-shot accuracy improvements when transitioning from iron sights to laser-equipped revolvers in low-light scenarios. The compact dimensions make it compatible with most J-frame holsters and speed loaders.
