If you’re not ready to carry a gun with a round chambered in a proper holster, you’re simply not ready to carry a gun for personal defense.
Check out this video of a close quarters knife attacker who is able to land repeated strikes on an Armed Professional while several other members of his agency take time to present and load their guns before (finally) shooting and stopping the attacker.
Note that at 55 seconds into the above video the officer closest to the attacker has his weak hand ON the attacker’s shoulder or arm and could possibly have stopped further strikes while drawing and using contact shooting techniques to stop the threat, had a round been chambered in his pistol. Instead, his training and method of carry required that he let go of the attacker and use his weak hand to chamber a round, delaying his response significantly.
Carrying a defensive gun with an empty chamber at the very least will delay your response to violence. In some cases, it may prevent you from being able to respond at all. To learn more about the failures of Empty Chamber Carry, check out this Personal Defense Network Video:
