The Tyrant CNC Magazine Extension, +3 Rounds, in blue for the SIG P365 XMacro (Tyrant CNC part no. TDP365MAGEXBLUE) adds 3 rounds of 9mm to the 17-round XMacro magazine. That takes the capacity to 20 rounds plus one in the chamber. Tyrant machines it from 6061 aerospace-grade aluminum and finishes it in blue. The NoBak retention plunger installs the extension in about 10 seconds without tools, and it comes off just as fast. The profile is sized to match the P365 frame so it does not add bulk under a cover garment.
