Grandpa's Service Pistol

Any weapon left to you in a will by a relative. Not necessarily a pistol, or even a service weapon, but usually. Generally left with an instruction not to use it for anything retarded. Usually in very good condition.

So named because of the stereotype of a grandfatherleaving his favorite grandson his service pistol.
