What an interesting topic this is.
We know that, to best defend ourselves and our loved ones, we must be ready, equipped and know what to do if necessary. Winning and surviving in self defense is about having the edge in the fight, whether that is in time, equipment, skill, and perhaps even in luck. We need to give ourselves the edge to win.
Take a moment and view the video first.
As discussed in the video, there is no doubt that not having a round in the chamber can put us at a great disadvantage and at risk. So why, then, is having a round in the chamber something we hesitate to do? After all, we carry a gun to be able to defend ourselves so naturally we don't want to put ourselves at greater risk, so why do so many choose to do exactly that?
But fear can also cause us to make decisions and choices without fully understanding the issue and the ramifications. We then make emotional decisions and not ones based on complete, accurate information and perhaps ones that are not in our best interest. We do so because of fear. We fear having a negligent discharge and someone getting hurt. This is a good thing to not have happen, so being concerned is natural and healthy. It is only responsible for us to do everything we can to prevent it from happening.
I believe that the KEY factor in this decision is CONFIDENCE. This is where both the question and the answer lies. Your level of confidence in knowing your gun, having it secured and under your control at all times and handling your gun is directly related to your confidence and willingness to carry your defensive handgun with a round in the chamber.
You are the keeper of your confidence and you are the only one that can raise it. Committed practice and experience is what can and will raise your confidence. Do your homework and due diligence in selecting the proper holster and equipment to minimize negligent discharges. Practice holstering and unholstering your unloaded gun to gain confidence and skill. Practice shooting as much as you can so you know everything your gun can do and everything it can't do.
Carrying a gun is serious business, with serious consequences. If you are going to carry a gun, you need to be READY to carry one and ready to use it. If you are not, then perhaps you should wait until you are. Ready means being mentally prepared; it means you are trained, comfortable and competent to to carry and use your gun. Anything less, leaves you and others at risk.
Of course, each one of us makes our own decisions and we each have unique factors in our lives that influence them.
