Do the different gens take different mags or are they all the same. Talking about Glock mags. Thanks. JR11-18-2010, 13:35The Gen4 mags are required for use in a Gen4 gun. You can use the current mags in an older gun. Older mags may or may not work in a current gun. vBulletin® v3.8.7, Copyright ©2000-2014, vBulletin Solutions, Inc.
