Product Description

The Tyrant CNC P365 X-Macro +3 Magazine Extension in Flat Dark Earth (TD-P365MAGEX-FDE) increases the capacity of factory Sig Sauer® P365 X-Macro 17-round 9mm magazines to a total of 20 rounds. Engineered for tactical operators and competitive PCC/concealed-carry shooters, this precision base pad extension provides immediate round-count capacity expansion while adding ergonomic grip purchase to the lower frame handle.

Precision CNC-machined in the USA from 6061-T6 billet aluminum and finished in a durable Flat Dark Earth (FDE) anodized protective coating, the extension features Tyrant's signature tool-less retaining pin architecture. The integrated plunger pin design allows quick attachment and removal from factory steel magazine bodies without set screws, specialized tools, or floorplate damage during routine cleaning.

Including a custom extended high-tensile power spring to guarantee proper follower pressure and last-round bolt lockup, the TD-P365MAGEX-FDE delivers reliable feeding dynamics, balanced extra weight for faster gravity drop-free release, and custom color-matched aesthetic staging.
