This is a bit off topic but as a newbe carrying, my mindset if robbed is to only use the gun as a very last resort. Please correct me if I am wrong, but I hear is someone is trying to rob you and asks for your wallet, the correct response would be to reach for your wallet but really your gun and come out firing. .... I tell you again my mindset is to only use gun as last resort.
Last resort is the right answer... but it's not a binary question.
Last resort is a perfectly good start... after all, what if it's a 10 year old girl waving a envelope opener at you demanding you wallet and cellphone? Are you just going to whip out your gat and start blasting?
No. No you are most certainly, unequivocally... not.
What if you are surrounded by six nasty looking bangers and you have a serious feeling you are going to get physically attacked if you hand over your wallet and cellphone anyway? At what point is last resort?
What if you are petite elderly lady and one pint size 20 something banger wants your purse?
It starts getting a little blurred.
In your class you should have been taught about opportunity, means and intent. You should also have been taught about disparity of force.
The 10 year old has opportunity and intent, but she weighs nothing and her weapon is about useless against a teenage boy and upwards.
Six gang bangers... they don't need weapons to hurt you. They have size and numbers...
A petite little old lady is going to be no match 20 something male with reasonable fitness level.
Layer that with...
If it's one guy and you think the guy is going say, stab you anyway vs. if you you are sure enough handing over whatever they want will end the situation without you getting hurt...
You should also have been taught about reasonable man doctrine.
If the class you took was the state mandated one, be aware that's not training and it's not enough - it's the bare minimum according to the state. It's our responsibility for training and understanding the law.
I would recommend starting with the NRA's Personal Protection Inside The Home and the Outside The Home Courses as solid foundations to self defense and include sections that have to be taught by specific firearms attorneys or Law Enforcement Officers.
There are of course many good instructors and schools out there that do comprehensive training so ask around your area, but the NRA ones are done nationally and are a very good start, so easy to recommend.
