Thanks all,
It's a Beretta BL4 20 ga that's in pretty minty shape...not a super fancy gun by some people's standards, but it has some history and is plenty fancy to me and it's also a hard-to-find configuration (O/U for less than a mint that weighs less than 6lbs)and I have no intention of doing anything to harm it--hence the question, I want to figure out what my options are before deciding on a course of action (if any). Don't worry, no shock-and-awe tactics here!

There are no plugs in the leather, so I'll try a stud finder (and maybe a magnet?) to see what I'm working with. If all else fails I can always use one of those velcro-on pads.
Thanks all,
Dave
