In this episode of Gun Stock Reviews, we went to Marty Enloe of Enloe Customs, with my newest acquisition, a Police Trade In Glock 17 Gen 3. When you pick up a used pistol, I would recommend that you have a qualified gunsmith check it up for you and make sure the pistol is safe to be used. This is what Marty did for me and we are ready to do a project with this pistol.
