Produced by Sig Sauer themselves, this air pistol was designed to be as accurate as possible to the real thing. The construction is full metal, making the pistol robust and reliable and giving a realistic sense of weight and balance. The 22 mm weaver rail under the front of the barrel is designed to facilitate the attachment of lasers or torches. The action is semi-auto blowback, which is very precise and realistic, and the barrel is threaded for the fitting of a silencer or muzzle brake.
