All I have to say is Israeli Air Marshals don't "Israeli carry". Because it's dumb.You definitely need to practice dealing with failures but having one already in the chamber is always going to be faster than not having one and having to draw and chamber for any given person. You can try to spin it anyway you want but Israeli carry is an unnecessary handicap. The fastest person deploying his/her pistol using the Israeli carry method will still be faster if they already have a round chambered. (Until their training scar kicks in and they still rack the slide out of habit ejecting an already chambered round for no reason.)
