gee i have bad news for people who think a gun will stop a mugger with a knife already out

professionals have simulated it with padding and simulated weapons, knowing what will happen in advance

and in a distance less than about 20 feet or a second and a half roughly,

the attacker with the knife always got a stab in before the defender could draw and bring the gun to bear for a shot

dont bring a gun to a knife fight

improve your footwork

its on youtube, yall can look it up
step 1 is make distance/time, then you can think about the weapon part
