GLOCK® Back Plates
I started making these to solve a real problem a friend brought to me. None of the back plates that he could find for his pistol would stay in place for even a few sessions at the range. He also really resented paying $50 for a fitting that wasn't even close to right.
DDR rear cover back plates are machined from solid aerospace titanium to extremely tight tolerances for a precise fit. They will not fall out of your gun. DDR back plates fit all GLOCK pistols, except the subcompacts.
