Used??? Certainly... Many many times... First I used and abused it to make sure it would be reliable if called upon up to and including discharge against a human predator...
I use it when I step out front and shoot amongst the pack of yotes in my garbage that my house dogs think they can handle...
I use it for the feral cats in the barn too...
But inside the home, I use it a few times per month...
Any time an uninvited person arrives that I cannot immediately identify is met at the door by me with my shotgun hid behind the door, if i even open it up...
Once identified, and I choose to invite the person in, they will see I am armed as I prop my gun on the wall nearby...
this is also followed by a typical "You really need to let me know you are coming in advance..." lecture...
I am not the consummate host of uninvited social visits and do take offense at those who think everyone invites this with open arms...
Have I ever fired upon anyone? Nope... I have "stood my ground" a few times while armed and a few of these the person on the hot end of the gun knew it to be so...
