Your in the fight,you do not even really know how they got this close,:
Does your holster have a retention system, other than you and your wisdom?
Do you use a thumb and bail that if you are in a physical altercation will keep your weapon with you?
Do you use a soft holster that sometimes comes out of your waistband when you pull on the weapon?
Do you turn the belt hook around so that it catches the underside of your belt?
If you go hands on,Do you know if you can retain control of your weapon?
