Tyrant CNC Magazine Extension Features The Tyrant CNC Magazine Extension adds 3 rounds of 9mm capacity to the Sig Sauer P365 X Macro s 17-round magazine bringing total capacity to 20 plus 1 for shooters who want more rounds on tap for personal defense. CNC machined from 6061 aerospace grade aluminum the extension is engineered to handle the stress of repeated use without deforming or cracking. The dimensions are specifically matched to the P365 frame minimizing the chance of printing through clothing during concealed carry. Unlike many extensions it functions reliably without requiring a power spring reducing the risk of miss feeds or jams that can plague poorly designed add-ons. Installation relies on Tyrant s proven NoBak retention plunger technology which lets the extension slide onto the bottom of the magazine and lock in place in 10 seconds or less with no tools required. Removal is just as simple requiring only a push of the plunger to slide the base plate free. Finished in gray and weighing just 0.3 ounces the extension adds meaningful capacity without noticeably changing the balance or feel of the magazine in hand. Whether for range use or everyday carry the Tyrant CNC Magazine Extension for the Sig Sauer P365 X Macro is available for sale at GrabAGun.
