Shadow Systems is now offering the new CR920X magazines for sale. This magazine fits our CR920X and shorter CR920 frames. – The magazine will protrude below the grip on CR920 frames but is still fully functional. Many who EDC the CR920 will find that the 15-round magazine makes the perfect reload for the back pocket. (A grip sleeve to provide full grip in the CR920 will be available later this year). – The CR920X magazine is compatible with our +1 magazine extension available HERE. We do not recommend use of the CR920 +3 extension on this tube with the standard spring that comes in the magazine as spring pressure may become too low. (We will be offering a dedicated +3 extension and spring later this year). – Our engineers chose to use magazine springs far stronger than those found in competing designs. This spring power provides extra insurance with a wide range of bullet weights and in compromised firing positions or when the gun is dirty. We spared no expense on the quality of the magazine by incorporating a premium ultra-slick nickel Teflon finish.
