Just saw a 10 round .45 cal magazine for sale on one of the typical sites. It looked to have the typical "flush fit" flat bottom instead of looking like it would over extend the grip. My question is since they can make a 10 round .45, why is it that you don't find an 11 round or higher 9mm single stack magazine? Its probably just due to a lack of demand or need in any competition class but I sure would be interested. Thanks Wanna kill these ads? We can help!
