This sounds like The Asylum's mockbuster version of "Runaway Jury" (they're the outfit who did "American Warship" in imitation of "Battleship").
Remember the "Runaway Jury" movie? The novel was about big, bad tobacco lobbyists, but the screenplay was changed to big, bad gun lobbyists. Checking the Wikipedia entry for the movie:
Budget $60 million
Box office $80.2 million
It was considered a disappointing performance.
I don't think there's enough die hard gun control fans to make this movie go anwhere.
In the 1959 Gallup Poll there was over 60% support for a ban on handguns.
In the more recent Gallup Poll there was maybe 25% support for a ban on handguns.
The gun control lobby is losing.
Maybe The Asylum could make a mockbuster copy of 'Miss Sloane' and call it 'Carrie Nation' about a noble prohibitionist fighting the liquor lobby. Maybe throw a sharknado in the plot for good measure.
