MAGPUL AMAG 21 SG9 P320 MAGAZINE - 9MM - 10 ROUND CAPACITY - 21 ROUND BODY - BLACK

Magpul AMAG 21 SG9 P320 Magazine: Compliance with Elite Performance

The Magpul AMAG 21 SG9 P320 Magazine is designed for shooters in restrictive states, offering a 10-round capacity within a 21-round body for 9mm ammunition. This magazine is modified with a proprietary in-house block and rivet through the baseplate to ensure compliance with local capacity laws, ideal for legal use in regulated areas like California. Constructed from heat-treated stainless steel with polymer sub-components and a black finish, it ensures durability, corrosion resistance, and reliable performance for SIG P320 and M17 pistols.

Engineered for full-size, compact, and sub-compact SIG P320 variants, including M17 and M18, this magazine retains the handling benefits of a 21-round body, enhancing grip and reload efficiency while adhering to legal standards. It features a high-visibility, controlled-tilt orange follower, a stainless steel spring, and rear-facing witness holes starting at five rounds for quick ammo checks. The flared polymer floorplate, removable for easy cleaning, includes a paint-pen dot matrix for custom markings, making it perfect for range or tactical use.

The permanent 10-round block guarantees compliance without compromising the magazine’s robust functionality, backed by Magpul’s rigorous drop-test durability. Ideal for range training, concealed carry, or home defense in capacity-restricted regions, this Magpul AMAG reflects the brand’s commitment to quality and innovation, proudly made in the USA. With its lightweight alloy design and proven reliability, it’s a top choice for P320 owners seeking compliant, high-capacity performance in a sleek black finish.
