Sig Sauer P365 XMACRO LEGION MAG CATCH ASSEMBLY 8901413 UPC 798681677955
Product Description
The Sig Sauer P365 XMACRO / AXG Legion Magazine Catch Assembly (8901413) is a complete factory replacement mag release kit engineered specifically for the wider grip geometry of the Sig P365 XMACRO and P365-AXG Legion grip modules. Manufactured directly by Sig Sauer to original equipment manufacturer (OEM) tolerances, this assembly restores factory-fresh retention, crisp release mechanics, and slick drop-free magazine operation.
Precision-machined from heat-treated high-strength steel and black composite components, the 8901413 kit includes all necessary internal small parts to completely rebuild or reverse the orientation of your magazine release. The textured magazine release button matches factory frame stippling and contours, ensuring a tactile interface that prevents accidental magazine dumps while enabling rapid index finger or thumb actuation during high-speed reload cycles.
Unlike standard micro P365 magazine catches, this assembly features the updated geometry and extended engagement lug required to function correctly inside XMACRO and AXG metal/polymer frame modules. Ideal for armorers rebuilding worn lower components or users reversing the control for left-handed operation, this kit guarantees positive lockup with all factory 17-round XMACRO magazines.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct factory fitment for Sig Sauer P365 XMACRO, P365-AXG Legion, and aftermarket XMACRO-pattern grip modules. (Note: Specific to XMACRO/AXG width geometry; not compatible with standard subcompact P365, P365X, or P365XL slim grip modules).
- Clear the firearm, remove the magazine, and remove the Fire Control Unit (FCU) from the grip module according to factory field-strip procedures.
- Depress the magazine catch stop wedge internally through the magwell channel using a small armorer pick or 1/16" punch.
- Slide out the old magazine release button, spring, and retainer stop from the side of the grip module.
- Insert the new Sig Sauer 8901413 catch, spring, and stop into the desired side of the frame (right-handed or left-handed configuration) until the retention wedge clicks firmly into place. Re-install FCU and perform function checks with an empty magazine.
