If I may be glib and dismissive for a moment:
Gunservant has a nice article discussing the idea:
Empty-chamber carry. Some people refer to it as Israeli Carry (which is funny because you don’t actually carry an Israeli with you), and among the naïve and the uninitiated this method of carry is the hotness. On the one hand I blame the lack of confidence that new firearm carriers experience when they just start strapping a handgun to their bodies for the first time. Everyone starts somewhere, and this anxiety is completely understandable. On the other hand there are certain instructors (a term looser than Charlie Sheen’s morals) who actively teach this method of carry, for completely bullshit reasons, usually demonstrated with more hissing than a pit full of angry Mozambican spitting cobras.
The “reasons” given as to why Israeli/Empty-chamber carry is supposedly the way-to-go are as follows (you may want to sit down for this):
- Carrying a firearm with a round in the chamber is unsafe. This leads to negligent discharges, which cause injury and death.
- If your firearm is taken from you, you will be able to take it back from the criminal before he is able to chamber a round by employing some sort of martial art technique.
- You are capable of drawing, racking the slide, and firing just as fast, or even faster (I shit you not) than you would be able to if you were carrying one-up.
Oh boy…let’s start curb-stomping these in sequence.
