Prepare a charcoal grill for direct and indirect cooking over medium-high heat.
In a large mixing bowl, combine the salt, black pepper, chili powder, garlic salt, cumin and flour. Dip each turkey leg in the seasoning mixture to evenly coat.
Cook
Place the turkey legs on the grill and sear on each side for about 3 minutes. Then brush each leg with the KC Masterpiece® sauce, close the grill lid, and cook for about 50 minutes, rotating/turning and re-basting each leg with more barbecue sauce every 20 minutes. Make sure the meat reaches an internal temperature of at least 165ºF.
Remove turkey legs from the grill and baste one last time. Serve with remaining barbecue sauce.
