Gunslinger, P.I. (2008)

After being warped through time in a meteor accident and setting up a name for himself in the 21st century in the field of private investigative work, a private eye named Garret "Gunslinger" Gallagher spends five days in an increasingly bizarre case involving an Irish mob boss and a modern-day cowboy who could pose as a threat to Gunslinger, his ex-convict partner, and his girlfriend, a talking car.
