Why only 10 round mags? ROG Tactical is a California based company and because of the stupid magazine laws here, even a business cannot sell magazines that hold more than 10 rounds (without an FFL, plus a High Capicity Magazine Permit...yes, very stupid!). If you live outside of California, ROG Tactical can have "High-Cap Mags" drop-shipped to you (Contact sales@rogtac.com, if you would like a quote for drop-shipped "High-Cap mags").
