This video reviews the Tyrant CNC +3 magazine extension for Sig P365X Macro magazines. The reviewer highlights that the extension is specifically designed for Macro magazines and will not fit standard P365 or P365XL magazines due to different base plate designs. While the extension reliably increases capacity to 19 rounds (comfortably 17+2, sometimes 17+3), the primary drawback noted is the failure of the slide lock back mechanism when the magazine is empty, attributed to insufficient follower tension. An upgrade to a stiffer magazine spring is recommended to resolve this.

Quick Summary

The Tyrant CNC +3 magazine extension for the Sig P365X Macro increases capacity to 19 rounds. However, it often fails to engage the slide lock back due to low follower tension. This issue can be resolved by installing a stiffer magazine spring.
