LOL Did you see the target I posted from the VERY FIRST TIME I handled and fired a rifle and a handgun?
I think I'll do ok.
And as for the psychological aspect of it, other than taking a human life (which I have admittedly never done, nor do I crave to) so much has been taken from me and life has shown me so much harshness that I can honestly say that if I were put in a position where it was MY LIFE or the LIFE OF ONE WHO IS THREATENING MY LIFE - I will pull that trigger without hesitation.
I would not ever consent to own a handgun if I had a question in my mind.
