Finally joined after a few months of lurking. I am a fairly new Glock owner, Glock 21 Gen 4, but by no means new to firearms. I want to say thanks to all of you for the knowledge I gained prior to purchasing my Glock and AACK. This forum has a plethora of wisdom and insight. I am continually learning from it and only hope I can add some information as I learn and grow into the above weapons. Thanks for a great forum. Wanna kill these ads? We can help!
