Thompson Center Arms G2 Contender or G2 Contender

After watching Hard Target i saw the gun and thought "That gun would be slick in Fallout: New Vegas".
Emil Fouchon (Lance Henriksen) prominently uses a Thompson Center Arms G2 Contender single-shot pistol as his weapon of choice throughout the movie, chambered to fire the .45-70 cartridges seen hanging on the loops of his belt. The gun is routinely shown blowing things up whenever it's fired,This same model gun was previously used by Philip Kwok as Mad Dog in John Woo's earlier movie Hard Boiled.
