Smith & Wesson, M640, .357 Mag, 2.13 inch, 5 Round, Cerakote, Tritium

The Smith & Wesson M640 brings the classic J?Frame revolver into a modern defensive package, with a 2.125" stainless steel barrel finished in black E?100 Cerakote, a five?round stainless cylinder with Black PVD coating and a double?action only, concealed hammer design that makes it a reliable small revolver for concealed carry and as a duty backup; chambered for .357 Magnum while running equally well on .38 Special +P, this compact S&W carries 5 rounds, weighs about 23 oz and measures roughly 6.63" overall so it stays manageable on a belt or inside the waistband, and the synthetic black finger?grooved grip and 1:18.75 RH twist rifling help tame recoil for controlled follow?ups. The M640 line is part of Smith & Wesson's rugged J?Frame family known for simple, durable operation, and the tritium front and rear night sights give immediate target acquisition in low light scenarios from close quarters to vehicle and home defense; as a regulated firearm it requires an FFL transfer and appeals to those who want a compact .357 Magnum revolver with proven reliability and clear defensive application.
