Magpul Industries Corp Mag1464Sst Amag 15Rd 9Mm Fits Sig P320 Silver Stainless Steel

The Magpul AMAG 15-round 9mm magazine for SIG P320 Compact handguns bridges the gap between polymer innovation and the durability demands of metal construction. When engineering physics requires steel over polymer, Magpul builds magazines with the same rigorous quality standards that define their polymer lines—and the AMAG 15 SG9 proves it. Built with a stainless-steel body and polymer sub-components, this magazine delivers the corrosion resistance and longevity serious shooters need, whether you're running drills at the range, training for duty carry, or keeping a reliable backup mag in rotation.

Magpul engineered the AMAG 15 with a controlled-tilt follower for consistent, precision feeding on every round. The stainless-steel spring maintains exact tension through hundreds of load cycles, resisting the corrosion that can degrade performance in harsh environments or humid storage. The flared floorplate comes out easily for cleaning—field stripping a magazine takes seconds, no tools required. Capacity indicators start at the 5-round mark and step up in single-round increments along the spine, so you always know what you're carrying. A paint-pen dot matrix on the body lets you mark loads and configurations at a glance, a simple feature that pays dividends in training or duty use.

Made in the USA, the AMAG 15 SG9 is compatible with all P320 Compact frames. If you shoot a P320 and want a steel-bodied magazine that won't let you down, this one earns its place in your kit.

Frequently Asked Questions

Will this magazine work with all SIG P320 Compact models?

Yes, the AMAG 15 SG9 is compatible with all P320 Compact frames.

Why choose a steel magazine over Magpul's polymer options?

The AMAG 15 uses a stainless-steel body when the engineering demands of the design require metal construction. The stainless steel provides superior corrosion resistance, particularly in humid environments or long-term storage, while the spring maintains exact tension through repeated loading cycles. Magpul built it to the same reliability standards as their polymer lines.

Is the floorplate removable for cleaning?

Yes. The flared floorplate is designed for easy removal without tools, making field stripping and routine maintenance straightforward.

How do the capacity indicators work?

Witness windows begin at the 5-round mark and continue along the spine in 1-round increments, so you can see your round count at a glance. A paint-pen dot matrix on the body lets you mark specific loads or configurations for quick identification.
