Yes dh does for farming purposes, they are not kept in the actual house though, but elsewhere on the property in a secure place. Cartridges are also kept in a separate place to the guns. He rarely has the need for using them though (rodent population kept at bay by 4 resident thugs farm cats, and an eager terrier) and he dosent shoot for pleasure purposes.
We also have a few very old antique guns that belonged to dhs ancestors, these have had something done to them though so they can no longer be shot and are therfore secure and safe. Two of which are on loan to a museum as are rare.
A friend of ours has several but these are again older ones and are for shows, displays and reenactment purposes, some of them have been used in movies and TV programmes before.
