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 15 SG9 is a 15-round SIG P365 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.
