It's 3:00am. Your house is dark since all the lights are off. The silence is broken with the violent sound of a door being kicked in then multiple footsteps in another room....you know that noone else in your family or acquaintance should be in the house... Next to you is a loaded 12 Gauge shotgun pump action with 6 cartridges loaded. Also next to you is your trusty .45 with 7 rounds loaded. Assuming both are loaded with the ideal self defense rounds and... Assuming both are 100% reliable....and in this scenario....You can only choose one. Which do you instantly choose for this emergency and why? I'm wanting to know what you guys as experts (or at least compared to me) think.
