The AMAG 21 SG9 is a 21-round 9mm handgun magazine for the SIG P320 family of pistols, featuring a heat-treated, stainless-steel alloy body with polymer sub-components. These magazines include Magpul's proven features: high-visibility controlled-tilt follower, stainless-steel spring, and easily removable flared floorplate for maintenance. The paint-pen dot matrix allows for identification marking, while capacity-indicator windows start at five rounds and continue along the spine in single-round increments up to 21.
The high-visibility controlled-tilt follower works with the stainless-steel spring to enhance magazine longevity and ensure consistent slide lock on empty. The flared floorplate enables quick disassembly for maintenance, while the capacity windows provide clear round counting when the magazine is outside the magwell.
