SIG Sauer is excited to offer this original equipment manufacturer (OEM) factory replacement magazine. This magazine is designed to be compatible with SIG Sauer P320 Legion models chambered in 9mm Luger. The magazine holds 10 rounds and is made from steel. This magazine will fit and function as reliably as the original magazine included with your SIG Sauer firearm. Whether carrying more magazines for self defense/duty use or spending more trigger time at the range squeezing the trigger having extra magazines on hand is always a winning idea.
