Sig Sauer P365-XMACRO 9mm 10-Round Pistol Magazine 8901466

Overview of the SIG SAUER P365-XMACRO 9mm 10-Round Magazine | 8901466

When your state has magazine capacity restrictions, or when a compact carry profile matters more than maximum round count, the SIG SAUER P365-XMACRO 10-Round Magazine (MPN 8901466) gives you exactly what you need. It is the factory original magazine built to the same tolerances as the magazine that shipped with your pistol.

Steel-bodied and finished in black oxide, this double-stack magazine holds 10 rounds of 9mm Luger and fits flush with the grip of the P365-XMACRO platform. Side witness holes let you confirm loaded capacity at a glance without removing the magazine from the pistol.

The polymer baseplate features deep finger channels that make emergency reloads faster and more positive under any conditions. Concealed carry permit holders, off-duty law enforcement officers, and competitive shooters working within capacity limits all depend on this magazine to keep their pistol performing.

Key Features

• Factory OEM Construction: This is a genuine SIG SAUER magazine manufactured to exact factory tolerances, ensuring the same fit, feed, and reliability as the magazine your P365-XMACRO shipped with.
• Steel Body with Black Oxide Finish: The steel body provides durability under daily carry and range use. The black oxide finish resists corrosion and gives the magazine a clean, low-profile appearance.
• 10-Round Capacity: Holds 10 rounds of 9mm Luger in a double-stack configuration, meeting capacity restrictions in many U.S. states while maintaining a flush fit with the pistol grip.
• Side Witness Holes: Visible round count indicators on the side of the magazine body let you confirm remaining capacity without dropping the magazine from the pistol or a pouch.
• Textured Polymer Baseplate: The deep-channeled polymer baseplate provides a positive grip for emergency mag swaps and stands up to repeated drops without cracking or deforming.
• High-Visibility Yellow Follower: The yellow follower makes it easy to confirm an empty chamber during administrative handling and range sessions.
• Made in USA: Stamped on the body, confirming domestic manufacture to SIG SAUER's specifications.
• Wide Platform Compatibility: Fits six distinct P365 pistols including the P365-XMACRO, P365-AXG LEGION, P365-DH3, P365-FUSE, P365-FLUX, and P365-XMACRO COMP. See the Compatibility section for the full list.
