I have a G-17 Gen.1 that I need to have updated with current factory parts. Does anyone know how to contact Glock to have them do the updates and the cost. I heard that if I send them the pistol they will do it for free. The Glock website only gives a address and phone number in Georgia, but no email support. Also if it is possible to have them update the frame to a 3rd Gen. with finger groves and rail for an additional cost. Has anyone ever had this done before?
