A defined legal term in New Jersey and New York, though with subtly different meanings. In New York,

“[c]ommunity gun” shall mean a firearm that is actually shared, made available, sold, exchanged, given or disposed of among or between two or more persons, at least one of whom is not authorized pursuant to law to possess such firearm.

But in New Jersey,

“community gun” means a firearm that is transferred among, between or within any association of two or more persons who, while possessing that firearm, engage in criminal activity or use it unlawfully against the person or property of another.

Not to be confused with community property guns, for instance. The term was new to me, so I thought I’d pass it along.
