I have been here quite awhile. I have searched this site as well as many others, and have yet to get a positive response. Is there ANYONE who has ever even seen a Glock with the serial number prefix MD? Does anyone currently own one? Does anyone have any information on this prefix? Any help is surely appreciated. It has become frustrating knowing that pistol is not 'one of a kind', or even rare from what I have gleaned, and yet I can not find even one person who has ever seen, handled or owned one. Thanks all!
