Hello! New member here. Enter at own risk. I'm thinking about purchasing my first handgun. I work for a Prosecutor's Office and some of our 'clients' are not God's best children. I will primary be using it for home defense and at the occasional concealed carry if I ever will feel threatened enough. I have never fired with a handgun, ie. pistol, revolver, but I am used to military assault rifles (M4, M16, etc) as I have a 10+ years of military experience. Hence, I have no true preference to a certain model, size, or type of ammo. However, I have carried, but never fired, a M9 pistol and found it to be quite cumbersome and way too big for comfort (I'm a big fella at 6'3, 230lbs). So I'm looking for a Glock which is a good option for home defense and the occasional concealed carry. I will probably only be at the range every six months or so to maintain proficiency as it will not be a hobby or a sport weapon. Any suggestion on a Glock model that might be a good match for me? Thanks in advance.
