It's a family relic. Belonged to his grandfather, who fought in WWII, and has been kept in the family as a keepsake of sorts. As such, it holds a lot of value to him and his family.

These are the kind of details that should go in your backstory.

I suppose it's okay to have, provided all it will be doing is sitting around gathering dust. After all, unless you're planning to add persona details later, you won't be using the gun in the bulk of combat in this RP. Of course, I'm going to need the strictest of assurances that you won't be whipping the gun out for anything less than friendly. I have been in at least one RP that went up in smoke because some nutter decided to stage a holdout in an RP when he suddenly felt like it.
