Interesting thread, especially for me being an Aussie and carrying is not an option here, I haven't read every reply, but i have a few questions and they're pretty general but if you want to satisfy my curiosity or critique my train of thought i appreciate the education, Aus and the USA are very different places despite the maccas and KFC....
So concealed carry, legal where you are (not everywhere i know) but do you have to wear a holster or can you carry in a pocket, handbag etc?
I have seen, on this forum, inside the waist holsters for snubby revolvers etc. but they all seem cumbersome and a quick safe draw might be difficult? especially under pressure?
Would you even try if the villain already has his gun drawn and ready? even if he's pointing it elsewhere?
There is no chance i would pull a gun to defend property, mine or an employers or any one else's, especially if the villain is obviously armed, they can have what they want, it's all replaceable.
Is open carry a thing anywhere? I would think open carry might lead to a larger weapon holstered correctly so therefore easier to access safely and faster?
If i were the customer hiding and was carrying i might definitely be tempted to shoot the villain in the back while he is preoccupied, no problem there, if it ends the threat i wouldn't lose a moments sleep either.
Here in Oz we don't even have castle laws and home invasions do happen, defending yourself in your home can lead to criminal charges, even civil action from the intruder, which is crazy but that's how it is. Having a license and hand guns doesn't allow me to shoot a home invader legally but if the safety my family is at risk the consequences ill be dealt with after, their safety supersedes any law that favours criminals ( And yes, i know by defending my family that makes ME a criminal but by necessity)...
