This is the Kimber CDS9 9mm 13-round magazine. 

Designed to deliver maximum performance, this 13-round factory magazine for the CDS9 is sure to impress.  

Kimber thought of everything with these magazines, from increasing the capacity and ergonomics with the extended floor plate to including a bright blue anti-tilt polymer follower for superior reliability and an instant reload notification. 

Pair all of that with the durable steel construction, and you have a magazine that is ready for anything! From concealed carry to home protection, the CDS9 can handle any task. 

Sure, 13 rounds is nice, but 26 or 39 is better! Add a couple of magazines to your cart and maximize your capacity.
