Description
The Smith & Wesson Model 637 Airweight is an ultra-light, 5-shot revolver chambered in 38 Special +P, purpose-built for concealed carry and personal protection. Building on the time-tested J-Frame platform, the 637 carries forward the original Chiefs Special Airweight DNA in a compact package designed to disappear in a pocket or inside-the-waistband holster. This SKU is the CA-compliant configuration and ships equipped with Smith & Wesson’s internal key lock.
At the heart of this J-Frame revolver sits a 1.88″ stainless steel barrel paired with a matching stainless steel cylinder, all housed in a lightweight aluminum alloy frame finished in matte silver. The revolver tips the scales at just 14.30 oz unloaded with an overall length of 6.30″, making it an easy-carry J-Frame for all-day use. A double-action/single-action trigger, exposed hammer for single-action precision work, and black finger-grooved synthetic grip round out the package, while an integral front sight and fixed rear sight deliver snag-free aiming for rapid close-quarters use.
Designed for backup-gun and concealed-carry roles, the Model 637 Airweight brings the reliability of the Smith & Wesson J-Frame platform to a compact, ultra-light package rated for full-power 38 Special +P defensive loads. This is the California-compliant version of the Model 637, equipped with an internal key lock.
