It may also be worth looking at firearms laws for the time and place of the adventure. Particularly if they're centered around Lovecraft Country in the 1920s, Massachusetts' laws are going to require investigators to associate with authorities in order to carry firearms other than rifles or full-length shotguns. Chapter 172 of the Acts of 1906 required authorization from a justice, mayor, or board of police for a person to carry a loaded handgun (either semi-automatic or revolver). Carrying one without a permit was punishable by a year in jail. In 1911, "loaded" was removed, so carrying any handgun without a permit was worth a year in jail. In 1922, "unnaturalized foreign born" were legally ineligible for permits. By 1927, the penalty for possession of a handgun, machine gun, or sawed-off shotgun, loaded or unloaded, without a permit could be as high as five years in state prison.
