loaded with 55grain fmj or soft poin bullets fast and frangible.....works well out to about 70 yds and won't be an over penetration issue....Of course get rid of the handle for a red dot and call it good....even with the muzzle flash/report you still have one hell of a trunk gun
PS Not totally sure on this but if you have a concealed carry license you have a pistol you can keep in your car out of site completely legally(again I think
well it is a pistol
)
