Never pull the trigger unless you fully intend to kill....
I have only a couple of guns, a new 20G and a Colt Cobra 38 special that I inherited when my dad passed away..The only thing I have killed with it is a coon. But sure hope I never have to point it at anyone, cause I fully intend to shoot for the largest body mass...it won't be a bluff...
Center mass is always best...
