One player requested that her Investigator have a derringer, which I allowed. I also told the players that firearms are freely available, but there are restrictions upon them. For example, since this is where your investigators are based...
Massachusetts requires a Carry Licence for handguns from 1906. Applicants need to be 15 years old, have a clean police record, demonstrate a legitimate need (Persuade roll), and pay a $2.25 fee. The licence is valid for 1 year. Illegal to carry on one’s person are blackjacks, brass knuckles, small clubs, or fighting knives of any kind. Long arms are unrestricted, but from 1925, a licence is required to possess a shotgun with a barrel length of less than 40 cm, and from 1927 a Machine Gun Licence is needed for owning full-automatic weapons. Possessing explosive ordnance requires a permit from 1919 onwards.
