The SIG SAUER P365 X-Macro Extended 9mm 25-round magazine brings serious capacity to one of the most popular compact carry platforms on the market. If you run a P365 X-Macro, AXG Legion, or FUSE and want to maximize rounds downrange without switching platforms, this factory mag delivers—25 rounds of 9mm in a double-stack configuration engineered specifically for SIG's modular grip ecosystem.
This isn't a universal magazine forced to fit; it's purpose-built for the X-Macro's grip module and seats flush with zero gap. If you're using a standard P365, P365X, or P365-XL, you'll see a slight gap at the baseplate when installed, but the magazine still functions reliably across all 9mm P365 variants. The steel construction and black oxide finish are consistent with SIG's quality standards, while the polymer baseplate keeps weight reasonable and provides durability for both range and carry use.
Practical design touches matter on a duty or defensive magazine. Rear witness holes let you confirm loaded capacity at a glance, and the orange follower makes it impossible to miss when the mag is empty—critical under stress. The black baseplate is easy to strip and service, and the overall layout plays well with standard P365 holsters and mag carriers designed for the platform.
Whether you're building a specialized training setup, want a deep-capacity mag for your X-Macro, or prefer fewer reloads at the range, this 25-rounder gives you flexibility without requiring a different gun.

Yes, it's compatible with every 9mm P365 variant: Standard, P365X, P365-XL, P365-X-Macro, P365-AXG Legion, and P365-FUSE. However, fit varies by grip module. It seats flush on the X-Macro, AXG Legion, and FUSE. On Standard, X, and XL grip modules, there will be a small gap between the baseplate and the grip—this doesn't affect function, only aesthetics.
You receive the magazine itself with the steel body, polymer baseplate, orange follower, and witness holes. SIG does not include additional baseplates or accessories with this product.
The orange follower makes it obvious at a glance. As you fire the last round, the bright orange sits flush with the top of the mag body. The rear witness holes also help you count rounds if you need a quick capacity check without unloading.
It's a factory SIG SAUER magazine built to the same durability standards as the gun itself, so it's equally at home in a duty holster setup, a competition rig, or on the range. The 25-round capacity makes it more practical for extended training sessions or as a backup mag in a competition belt.
