GLOCK recently announced that they will be officially debuting their new fourth generation, Gen4, models of the G21 (.45Auto), G32 (.357) and G34 (9×19) pistols at the 2012 SHOT Show in Las Vegas.
New updates for the Gen4 models include more refined ergonomics via a Multiple Back Strap (MBS) system for the grips. They’ll be available in short, medium and large sizes to let you customize your GLOCKs grip to fit your hand. They’ve also enlarged the Gen4’s magazine release catch and can now be switched for left hand shooters. They’ve also reduced felt recoil by using a dual recoil spring assembly as opposed to a single spring assembly. Stay tuned for more information from the 2012 SHOT Show.
