Shadow Systems Sgk-Crxmag-18 Shdw Cr920X Mag +3 Ext Blk

The Shadow Systems CR920X magazine extension is a straightforward way to bump your everyday carry or defensive firearm's ammunition capacity. This +3 extension transforms your standard CR920X magazine from 15 rounds to 18 rounds of ready ammunition—a meaningful gain for shooters who prioritize magazine-fed capacity without going to a significantly larger footprint. The extension arrives complete with spring, follower, and basepad, so you get everything needed to assemble it onto your existing magazine.

Shadow Systems designed this extension to work seamlessly with CR920X magazines. If you're running a Shadow Systems CR920X pistol or already have compatible magazines on hand, this is a direct upgrade that requires no gunsmithing or modifications to your firearm. Installation is straightforward: disassemble your magazine, swap in the extended spring and follower, attach the new basepad, and you're done.

For carry, competition, or range use, magazine capacity matters. An extra three rounds means less frequent reloads during practice sessions or—in a defensive scenario—a measurable increase in available rounds before the need to transition to another magazine. The extension maintains the overall reliability and function of the original magazine design while adding practical utility.
