Magpul AMAG 21 SG9 Sig Sauer P320 9mm 21rd Stainless Magazine

The AMAG 21 SG9 is a 21 round 9mm magazine for the Sig Sauer P320 with a corrosion resistant stainless steel body and polymer sub components. It brings Magpul's PMAG features to a metal mag: a high visibility controlled tilt follower for consistent feeding and a long life stainless steel spring.

Capacity indicator windows start at five rounds and continue up the spine one round at a time. The flared floorplate comes off easily for field cleaning, and a paint pen dot matrix lets you mark loads for fast identification. The extra capacity suits range and competition work.
