P-35HP,
I understand that you prefer to carry a single action auto-loader in condition 3. I understand your reasons. And I understand that you're free to have that preference and that you're not alone in that preference. The thing I don't understand is why you, and others who choose condition 3 carry, assume that in an emergency, when you may need to deploy your handgun in a hurry, you will necessarily have the full use of both your hands. Because with condition 3 carry, if you don't have full use of both your hands and you need to use your gun quickly, you will pretty much be out of luck.
As to the supposition that condition 3 has worked, first without a lot of detailed information regarding actual incidents, we really don't know that it does -- or at least we don't know exactly when or how it may or may not have worked in a lot of specific situations. We may be able to infer that condition 3 has been used in some situations and that the user has survived; but we don't know exactly what happened in each situation. Nor do we have any detailed information on the situations in which it didn't work. And, with all due respect, I don't believe that you can assume that condition 3 works for you unless you have been in an actual, violent confrontation and prevailed when carrying you sidearm in condition 3.
It also important to reflect that the tactical problems presented in combat or military operations are vastly different from those that will be presented to a private citizen attempting to defend himself from violent street crime.
I have talked with several people who have prevailed in violent encounters, and in at least a couple of those encounters, the defender in fact had to use his pistol one handed. Had those people been carrying in condition 3, they would not have been able to have prevailed. In any event, you can not make an appointment for an emergency, nor can you predict how an emergency will necessarily unfold.
In selecting your mode of firearm carry and in considering the way you train, I think it's important to remember that it is always conceivable that you will need to use your gun one-handed. I always recommend being able to diploy your gun quickly with one hand and training to shoot effectively with one hand -- both your strong hand and your weak hand.
