I'm in the mood for a new 9mm and am considering crossing over to the dark side and buying a Glock 17. I currently have a Beretta 92FS so the Glock seems to me like the opposite end of the 9mm spectrum (particularlly in terms of design). I'm looking at some other options as well but for some odd reason am being drawn to the glock like a moth to a flame. My son is so ashamed of me. Anyway, any Glock guys out there that can give me some of your experiences? I'm leaning towards new but would also consider used. Anything in particular to look for in a used Glock?
