Hello, Not that new to glocks. Owned my g27 3rd gen for over a year now. pretty proficent at shooting it, and acctually looking to buy a g22, but wanting to buy an aftermarket fully supported barrel. I want a fighting pistol, and was looking for .40 1911. (almost impossible to find). If I buy a g22 i would get the aftermarket barrel and possibly a stainless steel or tugsten guide rod. My g27 has glockmeister ss guide rod , extended mag release, extended takedown lever, and grip plug. My carry gun. Anyways. Looking forward to the wealth of info here. Wanna kill these ads?
