The Double Tap Controlled Expansion .357 SIG 115gr is a 20-round box of jacketed hollow point ammunition. Double Tap developed it for serious .357 SIG shooters who had no option other than a 125gr bullet. The company says the load combines speed, power and match grade accuracy. A flash suppressed powder is used for virtually no muzzle flash. Velocity is published from three barrel lengths.
