These are Factory made (Protech) Ivory Micarta Scales for a Protech Large Don Auto. Your exisiting Handle Screws will fit these scales. These Inlays allow you to switch out your current ones as an upgrade, or if you are looking for a change. No need to purchase another Large Don model; these inlays will save you a couple of hundred dollars. We ship these via USPS First Class Mail so the shipping is reduced to $5. (Full shiping is shown when you check out, however we will adjust the price when your card is processed.)
