Carrying a unloaded weapon does no good other than, if your a real good poker player, you can bluff your way out of trouble, hopefully, that is if the other guy/gal does not have a firearm. At this point all it is, is a piece of metal! I guess you could always use your gun as a hammer, or you could throw it at them. But be ready to be charged with "Brandishing" a weapon, which is against the law. If your pistol has a decocker on it , then charge the weapon, decock it, and then holster it and leave it alone. This way your ready for whatever trouble might come your way.
Remember, First and foremost, why your carrying a cw in the first place, to "protect yourself and your loved ones" Nothing more nor less.
Think about this, if the perp is 20 to 30 feet away from you, which is a good distance away, so you think, he/she can cover that distance in about 2 - 3 second's, a lot faster than you can pull, rack/chamber a round, and then find your target/perp and shoot!!! If you carry a revolver, then its different, still you have to draw, and a quire the target, hopefully while doing it calmly and not under stress, which we all know is not going to be the case. What people/CCW's don't understand is that you have to make a life or death decision, in a matter of seconds, which will forever change your life. Just remember things are going to happen super fast and that you want to be on the winning side of the confrontation.
