Problem with that is my 12g has 1 in the pipe all the time. No racking here unless I unload one in someone's Arse then rack the empty.
I would not keep that train of thought towards your 12g and home defense. One day that may make a bad situation worse for you.
I worry about my family not the legal action afterwards. If I shoot then it is to save my family or my life. I will state that in court if need be but he won't be able to make it that's for sure.
