Magpul
15-round stainless-steel AMAG for SIG P365-pattern 9mm pistols.
The Magpul AMAG 15 SG9 is a current-production 15-round magazine for SIG P365-pattern 9mm pistols. It gives P365 and P365X/XL owners a 15-round option without moving to the full 17-round X-Macro magazine, using a stainless-steel body and Magpul's user-configurable floorplate system.
The AMAG package includes grip-extension hardware for the standard P365 and X/XL grip lengths, plus a flat floorplate option for Macro-size frames. That lets one magazine body support multiple P365 grip modules, though users should test fit and live-fire function in their exact frame and magwell setup before relying on it for carry.
For shooters who want a buyable 15-round P365 magazine today, the AMAG 15 SG9 is the cleaner current catalog pick than chasing legacy OEM 15-round SIG magazines on secondary markets.
Add the Magpul AMAG 15 SG9 for SIG P365 to your build and see how it enhances your platform.
