This is a 3-pack of Magpul AMAG 21 SG9 9mm 21-round magazines for Sig P320, M17 pistols. 

Magpul has proven itself for many years with its PMAGs and is ready to do it again with the new AMAGs, this time for the Sig P320!

Constructed from corrosion-resistant stainless steel and featuring anti-tilt polymer followers, you can rest easy knowing that durability and reliability of these magazines will never be an issue. On the back of the magazines, you’ll find precision-cut numbered witness holes that provide instant capacity checks. 

As if all that wasn’t enough, Magpul finishes off each one with a flared and removable floorplate that features their signature paint pen dot matrix. With the P320 being versatile enough to fill almost any role, you can never have too many magazines!

These AMAGs for the Sig P320 will likely fly off the shelves, so we’d recommend adding a 3-pack to your cart before you forget!
