the cabelas gun scabbard that mounts on the roll cage is pretty popular with sxs folks. Ton of folks sell accessories for these things.
These are an option too, not sure what you intended purpose is.
https://www.scabbard.com/I bought gun mounts from suregrip for my sxs, they have a bunch of options for roll cages, etc.
This guy sells a lot of odds and ends for multiple makes, I've ordered from him and others I know have never had an issue.
