If I were looking for ''home protection''I think I would look at a Maverick''defender''.However, back to my Tamer[it has a 20''barrel too] and the subject of recoil pads-someone suggested usiing the sole from a beach thong-they are about 3/4''thick ,and I'm toying with the idea of using clear silicone to glue it one-if it would hold it on securely , it would fill in the voids from the ribs.
