For those that love the .357 Sig, we have the perfect loading for you. The .357 Sig was developed to match the .357 Magnum in speed and power using a 125 grain bullet (1450 fps). Recently there have been no options for the serious .357 Sig shooter to get this velocity. At Doubletap we have developed a loading that combines speed, power, and match grade accuracy. All of this and we use a flash suppressed powder for virtually no muzzle flash.
