My gun is my LAST resort. 1st is a security system, then two dogs, then the maze it is to get to the sleeping area of the house. If they (an intruder) decide they want to make it that far, well so be it. The last thing I want is "blood and bullets" all over my house or to have my family subjected to anything of the sort.
Tha last thing I ever want to do in this life is to shoot another person.
BUT...when all else fails and it is us or them I will not let my family be victims.
I really do think anyone who owns a gun for protection should be fully trained in the use of that gun. Safety is the biggest factor. Anyone who does not take it serious is just asking for major problems and is better off not having a gun in the home in the first place.
Be safe!!
