Why not a Zinc option for the compact versions?07/26/2017 3.81K views07/27/2017 Jeremy (anonymous) 07/27/2017 0 Comments I see you are not using Zinc for the ultra compact options? Why is that?Also, why is the cost no less if the case is made from a much cheaper material?Thanks 1 AnswerActiveNewestOldest admin Posted 07/27/2017 0 Comments The compact cases are CNC machined; the classic style cases are die cast like the originals.
