Magpul Magazine, AMAG 17 SG9,

When polymer won't work, Magpul's AMAGs will. The same reliability and consistency you expect out of their PMAGs, now available in alloy magazines. The AMAG 17 SG9 is a 17-round SIG P320 9mm handgun magazine featuring a heat-treated, stainless-steel alloy body with polymer sub-components. Magpul AMAGs come with many of their proven features, including a high-visibility, controlled-tilt follower, stainless-steel spring, flared floorplate that's easily removable for cleaning and routine maintenance, paint-pen dot matrix for magazine marking, and capacity-indicator windows which begin at five (5) rounds, and continue along the spine of the magazine in one-round increments.
