The Things folks have got to know is that there DD214's and Hunters safety certs mean little to nothing when it comes to knowing how to fight with a handgun and the laws regarding deadly force... qualifying 'Expert" in the Military or being a sniper qualified sounds great, but I ran Small Arms qualification for well over 20 yrs in all the Units I served with, both Rifle and Pistol, and I can tell you, none of it is teaching the skills you would need to not only survive, but win a gun fight.
I have qualified Expert Pistol my entire career, both 1911A1 and M9 along with qualifying a M4. and all it meant was I could pass a certain level of Marksmanship. I could hit "X" amount of targets with "X" amount of ammunition at "Y" distance under "Z" amount of time. Nothing more
None of it taught me manipulation,mindset or tactics or the biggest one of all... Avoidance..
If folks are smart, they would seek out additional training... as if you are unfortunate enough to be involved in a shoot (very low odds) it means you are about to be involved in the most important event in your life... you would want that extra training as there will be little need for it after the fact.
