RSM and Red Label (.338 WinMag O/U DR and 20 Ga) use same pad and sling stud hole location.
After I whittled that hole for the sling stud, I started using a large hole punch to make them prettier on subsequent pads.
Brown dye also touches up the edges all around and where hole was punched.
Either GALCO or ACTION brands are my favorites, leather & Velcro.
The GALCO is prettier without having to be dyed darker brown on butt end.
I have dyed some of the 2-tone ACTION pads all black.
