Sorry, I'm from Illinois. Looking at magazines and trying to understand the difference between 11102 and 11132 10 round ones. Depending on which picture is posted, looks like the 11102 is a short metal body with an extended poly base to make it fit Full Size 75's. The 11132 appears to be a full length metal body as is. Is this correct? If so, could the extended base on the 11102 be replaced with a "standard" base and result in a flush magazine for the compacts ?
