got this from the motor cycle board...this is pretty cool..: http://www.taurususa.com/video/taurus-theJudge-video.cfm Taurus 3" revolver 410/ 45 l.c. for CLOSE range defense in a vehicle they claim the rifled bore spins the .410 shot column opening the shot pattern immediately upon leaving the muzzle...designed for use in a vehicle at range to the pasenger side window.ck it out.
Saw that on the Outdoor Channel. It looks pretty good. I think keeping one in the car would be a good idea. A facefull of shot would certainly discourage a carjacker without endangering background traffic like flying 45 slugs would.
