Hi there I am rather new to buying guns that are used. I really don't know what I should be looking for when I get it or what kind of questions to be asking about it. I have a chance at getting a used Glock 26 with tritium night sights and two mags for 450.00 I have always gotten my guns new or well taken over one of my boyfriends guns. I can't really ask him cause this is his early Christmas present. I would appreciate all your input Thanks.
