If you need or want a 10 round magazine, you should try the PRI mag. A superb manufacturer for decades, PRI has recently built their own mags. Charlie's finds the PRI mags to be very heavy duty and a great addition to your arsenal.
PRi magazines are constructed of butt welded steel halves to create the best internal volume for the magazine. Includes Magpul anti-tilt follower with spring and push button floor plate. 10 round magazine is 3.125".
