This is the factory OEM Smith & Wesson CSX E-Series 9mm 17-round magazine. 

Just because your CSX E-Series pistol doesn’t have a full-sized frame, it doesn’t mean you can’t have a full-sized capacity! 

These 17-round extended factory magazines will ensure you’re ready to handle whatever may come your way. With a steel tower and an anti-tilt polymer follower, you’ll never have to worry about durability or reliability. 

Since you’ll have more rounds than you’re used to with a CSX, the side-facing witness holes will help you keep track of exactly how many you have remaining. The new CSX E-Series pistols are versatile enough to fill any role, from concealed carry to home defense, so the more magazines you have available, the better.

Grab a couple of these extended CSX E-Series magazines while you can!
