Smith & Wesson Model 637-2 Airweight .38 Special +P 1.88" DAO/SA Revolver
The Smith & Wesson Model 637-2 Airweight is a five-shot, J-frame revolver that balances lightweight carry with +P performance. Its aluminum-alloy frame keeps the unloaded weight to roughly 14.6 oz, while a stainless-steel barrel and cylinder add strength for sustained range use. This example combines the classic exposed-hammer Chiefs Special profile with modern safety updates, making it a practical choice for everyday carry or a solid addition to a J-frame collection.

Built on the time-tested J-frame, the 637-2 retains an exposed hammer, giving the shooter the option of single-action precision or smooth double-action work. The alloy frame significantly reduces weight without compromising durability, while the stainless-steel cylinder and barrel provide corrosion resistance.
This “-2” engineering change introduces Smith & Wesson’s keyed Internal Locking System and a transfer-bar hammer block, adding modern safety layers to the revolver’s classic mechanics. Despite its light weight, the gun is factory-rated for continuous use with +P ammunition, offering extra velocity in a compact package.
The 1.88" barrel, fixed sights, and black synthetic boot grip keep the profile minimal for discreet carry. The matte silver finish on both frame and cylinder helps reduce glare and resists everyday wear.
