I am moving within the same town (Malden). Sending my change of address form today, but does anyone know how long I would have to wait before I can purchase a new gun? The address change form is for my license to carry. Does the gun shop care? When they run my info, will it show my address? I just don't want to buy a gun only to find out it was registered to the old address because it was not updated in the system yet, and then I have to deal with more paperwork.
