Factory HK 12-round extended magazine for the CC9 micro-compact
Factory HK 12-round extended magazine for the CC9 (HK part 51000488). Solid steel construction with a corrosion-resistant black finish carries the same durability standards HK has applied across the VP9 and USP magazine lines, in a smaller footprint sized for the CC9's 0.99-inch slide. The orange follower gives positive empty-chamber indication, and rear witness holes let the shooter check remaining round count without dropping the magazine.
The extended floorplate adds a full pinky's worth of grip surface to the CC9, which materially improves recoil control versus the flush 10-round magazine. CC9 magazines are dedicated to the CC9 platform; they will not interchange with VP9, VP9A1, VP9SK, or VP9cc magazines.
