��. The million dollar question and is the question I get asked the most. First, I'm an Illinois resident and can't carry when in Illinois. I am licensed in every other state. When I do carry I personally prefer the 9mm...right now, I train on only two...M&P 9c and the FNX 9. I just received the Shield and will start my training regiment and it will be in my rotation soon. I don't recommend more than two within a rotation but I spend 15 to 20 hours a week training (my personal training) I'm more comfortable , more accurate with the 9. I instruct people to use the caliber they are most comfortable with regarding action, ability to handle, control....then train, train, train. And just don't shoot at targets...create situational objectives..stance...positioning...lighting...stress control...breathing...draw...and on and on. I can talk hours on this topic...and i do
If your carry weapon cannot be thought of as part of your body than you are not ready. (My only issue with handing out ccw permits) I can present my weapon no differently than scratching an itch...i do without a lot of thought...its just instinctive...it's apart of me. I tell people to be, not just proficient, but expert with a weapon and be able to use it effectively and safely is a combination of mind and body...that's what we train to.
You can argue about what is the best caliber...an argument than will have no winner. I work with an individual that can eliminate a threat with a .22 faster than I can blink. Try having the caliber argument with him...I promise you will lose.
Not sure I answered your question. ��
