Smith & Wesson Model 637 Airweight, .38 Special +P, 1.88", 5rd, Silver, Revolver

The Smith & Wesson Model 637 Airweight is a five-shot .38 Special +P revolver with an exposed hammer. Its aluminum J-Frame, stainless barrel and stainless cylinder bring compact dimensions and traditional single-action/double-action operation together for a straightforward carry or backup handgun.

This silver configuration has a 1.88-inch barrel and a 5-round cylinder. The single-action/double-action action and aluminum frame define its handling and construction. Select the exact barrel length and grip profile when comparing carrying accessories.

Short barrel and lightweight frame

The 1.88-inch barrel keeps the revolver to 6.31 inches overall. At 14.5 ounces, the aluminum-frame design limits carrying weight while retaining stainless steel in the barrel and cylinder. Holster selection should account for the exposed hammer and exact grip profile.

Exposed-hammer flexibility

The exposed hammer is the defining operational difference between this 637 and enclosed-hammer Airweight models. Its single-action/double-action mechanism supports either trigger mode. That traditional layout can appeal to shooters who want a compact revolver that still offers deliberate single-action range use.

Synthetic grips and integral sights

Synthetic grips and an integral sight system keep the configuration straightforward. There is no included laser on this version, and the cylinder holds five rounds. The revolver is rated for continuous .38 Special +P use, a useful distinction from models limited to standard-pressure ammunition.
