Smith & Wesson Military & Police handcuffs have a revolutionary finger activated double locking mechanism. There is no need to use a handcuff key to double lock the M&P lever lock handcuff. Double locking handcuffs prevent them from being tightened or loosened without a key. To double lock these handcuffs use your finger to pull up on the double lock lever until you feel a click. Once you feel the click, these handcuffs cannot be tightened or loosened without deactivating the double lock with a handcuff key.
Smith & Wesson lever lock handcuffs are available in two finishes: Satin Nickel and Black Carbon Nitride (Melonite). The Nickel finish handcuffs are silver in color and have a dulled or cloudy surface to ensure they are non-reflective. Shiny handcuffs can cause blinding glare or give up your position in tactical situations where cover is required. Nickel plating also acts as a protective layer against corrosion. The black carbon nitride handcuffs are also non-reflective. The black finish is deep into the metal, so the will not appear scratched and scuffed after heavy use. Black M&P handcuffs are also extremely rust resistant.
Smith & Wesson Military & Police handcuffs are sold with 2 keys, a warranty card and instructions. Smith & Wesson provides a lifetime warranty against manufacturer defects.
