Smith & Wesson Model 637 38 Special +P 1.88" 5-Shot J-Frame DA/SA Revolver w/Crimson Trace Laser

The Smith & Wesson Model 637 Airweight revolver is purpose-built for concealed carry and personal protection. Built on the classic J-Frame platform, this snub-nose revolver is chambered in 38 Special +P, feeding from a 5-shot cylinder and featuring a 1.88-inch stainless steel barrel with an overall length of just 6.30 inches.

This Model 637 pairs a matte silver aluminum alloy frame with a stainless steel cylinder and barrel, delivering a carry weight of only 15.40 ounces. The double-action/single-action action is driven by an exposed hammer, allowing both precision aimed fire and rapid double-action draws. Sighting is handled by an integral front blade paired with a fixed rear notch, a time-tested combination for quick target acquisition at close range.

A defining feature of this configuration is the factory-installed Crimson Trace Lasergrip in black polymer. The grip-activating laser provides an instant aiming reference the moment the revolver is drawn, making the 637 a natural choice for self-defense scenarios where speed and accuracy matter most.
