I've posted this before, and I will again. I HATED Glocks prior to Gen 4. HATED them. The polymer was just way, way too slick. I own three Gen 4's, a 23, 27, and a 19. I will say it is super easy to scratch up the Gen 4 finish, bit that doesn't bother me. I carry my guns, and shoot them. I don't mind wear marks. The texture, inserts, and magazine release are simply too much to give up if you go Gen 3, IMO.
