hey all new to the boards and to glock. i live in Pennsylvania i am looking for a good woods gun to carry on the ATV. and the G29 caught my eye. my question is i found a used one that looks new. i would bet there was not even a hundred rounds thru the gun. i can get it for $425.00. is there anyway to tell how old the gun is or what gen it is? is there a certian generation to stay away from on the G29`s.
