History
The first model was chambered in .38 Special and fitted with a standard barrel of 1-7/8 inch length.
The second model had a slightly heavier and longer barrel of 2-1/8 inch length.
A 3" barreled version was offered until 1993, when it was dropped from production.
In 1995 the model 642 was introduced which was made in aluminium and designated "airweight".
In 1996, S&W began chambering the 640 in .357 Magnum.
Because of the power of the .357 magnum cartridge, the frame is strengthened just in front of the cylinder release on those models.[2]
Design
The gun was constructed entirely of stainless steel.
Like other "J-frame" Smith & Wesson revolvers, it has a swing-out cylinder, but this model features a concealed hammer, and is part of the Centennial line.[3]
