The Model 637 is the 5-shot J-frame built with a stainless steel barrel and cylinder and an aluminum alloy frame with an exposed hammer. It has black rubber Uncle Mike’s Boot Grips. The two greatest strengths of this gun are its excellent accuracy and 13.5 ounce weight. Other strengths I would list are the rounded contours of the gun, ease of concealment, its simplicity of operation, and high production values in finish and fit. This particular model is the 637-1, the “-1” indicating that it is rated to handle +p ammunition. When I selected the 637 I really struggled with the choice between the 637 and the 642, the Airweight Centennial which is double action only. I settled on the 637 because its exposed hammer allows me to cock it for single action fire which makes for greater accuracy. The 642 is “snag free” and would be the better choice for pocket carry.
