This is a good topic though I have not read all 4 pages but what I have read there is a good amount of sense. I am not going to debate or condemn anyone's choice on what to carry as I have heard it said the first rule of an armed confrontation is to have a weapon. One thing to think about when making the decision time of year and what clothing is normally worn. Cold places when people wear heavy clothing small calibers less powerful rounds may not pernitrate to meat or vital organs. I would suggest that what ever you decided to carry make sure it is a weapon and round you can shoot accurately.

He who strike meat first and most usually wins.
I have been told that you can't miss fast enough to win a gun fight.

These are my thoughts on this so take it for what it is worth.

Just a guy.
