Well I look at this way. I'm pretty good with a pistol but for My better half EHHHHHHH. I showed her 4 things.
1.) Where the charging handle is.
2.) how to put a 30 round mag in a AR
3.) how to smack the side of the gun to make the bolt go foward.
4.) How read the switch that says Safe and change it to fire.
She has a CTC laser grips on the gun that comes on when she squeezes the grip. She also has 30 chances to pull the trigger, and the gun dosn't recoil as much as a pistol.
Plus for me I try not and bring a handgun to gun fight. Overpower, Control, Dominate the situation, and continue to take in Oxygen for the following day is what I have to have happen.
