Smith & Wesson Model 638 Airweight 38 Special +P 5-Shot Revolver

The Smith & Wesson Model 638 Airweight delivers reliable concealed carry performance in a lightweight aluminum alloy frame. This hammerless revolver eliminates snag potential while maintaining the proven reliability of the J-frame platform. The enclosed hammer design allows for smooth draws from pockets or tight holsters without catching on clothing or gear.

What Makes This Different

The Model 638 combines the strength of a stainless steel barrel and cylinder with an aluminum alloy frame, reducing weight to just 15 ounces. Unlike standard steel-frame revolvers that can weigh 20+ ounces, this configuration maintains structural integrity while cutting carry weight by 25%. The internal lock system provides additional security without affecting the revolver's external profile or operation.

Key Features

• Aluminum alloy J-frame reduces carry weight to 15 ounces
• Stainless steel 1.875-inch barrel and cylinder resist corrosion
• Hammerless design prevents snagging during draw
• Polymer grip provides secure handling in wet conditions
• Internal lock system adds security layer
• 5-shot cylinder capacity with .38 Special +P rating
• Compatible with standard J-frame holsters and speedloaders

Field performance centers on the .38 Special +P capability, allowing use of standard pressure loads for practice and higher-pressure defensive ammunition when needed. The 1.875-inch barrel provides adequate velocity for personal protection while maintaining concealability. Weather resistance comes from the stainless steel construction of critical components, while the matte silver finish reduces glare and wear visibility.
