When polymer isn’t enough, Magpul delivers. The AMAG 17 SG9 is a 17-round magazine engineered specifically for SIG P320 Fullsize frame handguns, offering the rugged reliability you expect from Magpul — now in a heat-treated stainless-steel alloy body.

Designed to handle the demands of real-world use, the AMAG 17 SG9 features a high-visibility, controlled-tilt follower for consistent and reliable feeding, paired with a corrosion-resistant stainless-steel spring for long-term durability.

The flared polymer floorplate makes for easy handling, removal, and cleaning, while round-count indicator windows along the spine let you quickly assess ammo levels in one-round increments starting at 5 rounds. The integrated paint-pen dot matrix on the baseplate allows for custom ID marking—ideal for range organization or duty use.
