About the Smith & Wesson Model 642

The Smith & Wesson Model 642 is a compact revolver built on Smith & Wesson's J-frame, introduced in 1996. Chambered in .38 Special +P with a 5-round cylinder. Featuring an aluminum alloy frame, this revolver achieves a notably lightweight package suited for everyday carry. The 1.9-inch barrel provides maximum concealment in a snubnose configuration, making this an ideal backup or deep concealment weapon. The double-action-only trigger mechanism provides a consistent pull stroke and eliminates the external hammer, creating a snag-free profile ideal for concealed carry situations where a smooth draw is essential. Weighing just 425g (15.0 oz) empty, this ultra-lightweight revolver is designed for comfortable all-day carry, though the reduced weight means increased felt recoil with full-power loads. Smith & Wesson has been producing J-frame revolvers for over seven decades, continuously refining the platform with improved metallurgy, ergonomics, and manufacturing techniques while maintaining the fundamental reliability and accuracy that has made their double-action revolvers the benchmark against which all others are measured.

The Model 642 Airweight is one of the best-selling concealed carry revolvers of all time, its internal hammer design preventing snags during draw from pocket or purse.
