Seriously, the thing to concentrate on is training, not some ideal magic-wand firearm that takes no training and hits its target every time. If I ever run into one of those I'll buy it. Until then, practice, practice, practice...and then more practice. Hey, it's your life at stake - isn't it worth a little time?
And remember the Amish warning; I mean you no harm, English, but you are standing where I intend to shoot...
I have a Taurus Judge and it will fire 410 shotgun shells. It does have a bit of recoil but with the 410 “handgun” ammo, she should be able to easily handle it. It is like having a shotgun in a revolver and it is. I love it and there is an availablity of ammo from squirrel shot to rifled slug and a special new PDX1 Defender ammo that is really bad. It will also fire 45 long colt ammunition with very minimal recoil.
