Purchased a Wrangler back around Thanksgiving of 2019. It was a terrible gun to shoot. A foot low and left at 15 yards. Sent it in to Ruger for service and they replaced it. New gun shot point of aim at 15 yards with half dollar groups. Much better. Haven't been to the range to shoot it since before Christmas. Shot it in a Bulls-Eye match yesterday and scored 794/900 with 24 X's. Top of rimfire class and high score overall. Now I need to clean it. But, I don't have a driver that will fit the grip frame screws. Are these just an allen head screw or something proprietary?
