“Allahu snackbar!”
No one wants to hear that at Walmart, then popping noises ..... so,
I only play a pistolero at the range and on FR, but most of us carrying concealed won’t have shotguns on our hips in the grocery store or wherever. Public places.
Unless you have time to run outside and pop your trunk, you fight with what you have: a pistol.
Yes, definitely:be sure of your target and what/who is behind it. And ditch your beloved milsurp pistol and buy something that reliably feeds hollow points.
Since ‘tunnel vision’ kicks in, just aim for center of body mass and make sure you re-holster ASAP so someone doesn’t shoot you.
Sound advice ...
