Hypothetically speaking, the year is 1998 and military member A, stationed in lets say Colorado, buys a handgun private party from military member B. Military member A gets orders to, lets say, England. No handguns allowed so military member A, home on leave to California, sells said handgun to friend. Fast forward to 2010, the friend never registered the handgun. Can it be made legal with out incurring the wrath of Sacramento?
