The Cool Guns Shadow Systems CRX 15-round 9mm magazine is a high-capacity reload solution purpose-built for the CR920X platform and compatible with shorter CR920 frames. If you're running a compact 9mm and want serious magazine capacity without sacrificing reliability, this is the tool that delivers—especially for those who carry a backup mag on duty or in the field.
Shadow Systems engineered this 15-round magazine around durability and performance in real-world conditions. The magazine uses springs significantly more robust than competing designs, giving you extra security across a wide range of ammunition weights and when shooting from compromised positions or with a fouled gun. The premium nickel Teflon finish on the aluminum tube means fast, slick operation and excellent corrosion resistance.
On CR920 frames, the magazine will protrude below the grip—a trade-off many EDC shooters accept gladly for 15 rounds of reload capacity in a pocket-carry footprint. The CRX magazine is compatible with the Shadow Systems +1 extension if you want an extra round in the magazine itself, though Shadow Systems advises against using their CR920 +3 extension with this magazine's standard spring, as pressure may drop below safe levels. (Shadow Systems plans to offer a dedicated +3 extension and matched spring later.)
Built for shooters who demand magazine reliability as a non-negotiable foundation, the Cool Guns Shadow Systems CRX 15-round magazine pairs modern materials with conservative engineering—no shortcuts, no guesses.

Frequently Asked Questions
Will this 15-round magazine fit my CR920 frame?
Yes, the CRX magazine is compatible with both CR920X and CR920 frames. On CR920 frames, the magazine will protrude slightly below the grip, but it remains fully functional and is popular with those who carry a reload in a back pocket.
Can I use the CR920 +3 extension with this magazine?
Shadow Systems does not recommend using their standard CR920 +3 extension with this magazine's stock spring, as the spring pressure may become too low for reliable operation. They plan to offer a dedicated +3 extension and matched spring later.
Is the CRX magazine compatible with any extensions?
Yes, the CRX magazine is compatible with the Shadow Systems +1 magazine extension.
What makes this magazine different from standard designs?
Shadow Systems uses significantly stronger magazine springs than those found in most competing designs. This extra spring pressure provides added reliability across a wide range of ammunition weights and in compromised firing positions or when the gun is dirty. The magazine also features a premium nickel Teflon finish for superior durability and corrosion resistance.
