Gunsmith Cats(1995)

Overview:

Rally Vincent and Minnie May Hopkins are just a pair of gun shop owners who do a bit of bounty hunting to make ends meet when a Bureau of Alcohol, Tobacco, Firearms agent comes to them. Using the threat of arresting them for their lack of a retail license for their merchandise and the resulting unpaid taxes, he forces them to agree to cooperate in a sting to break a gun running ring. They have an initial success, but that brings new problems as the ring's leader brings in a merciless assassin to eliminate these new enemies. It will take all their skill, allies and some luck to come out this crisis alive.
