I think that most would agree, the most common "self-defense distances" are between 5-15 feet. Let's suppose for now that is
correct...By the time the pistol could be cleared of the holster, pocket, purse, jacket...whatever and brought upward to a position
where the sights could be used and aligned on a moving target and a round fired, the attacker has had more than enough time to
react to the presence of the gun and have an incredible advantage over the victim...one that cannot be overcome. The attacker is
not going to wait for you to get into YOUR chosen position. That would be nice...but it ain't gonna happen.
If you feel you MUST have sights on a pocket pistol then you are not using the pistol the way it was intended. Accurate point shooting is the solution to the situation described above. I've heard the practice for this called by many names...Bill Drill...belly shots...quick draw...even "pocket shooting." Stand 5 ft. from a full man sized target with your hand properly gripping your pistol. Focus your eyes on a small spot just below where the breast bone would be. On signal, pull your pistol slowly and fire 1 round at that spot. DO NOT MOVE THE PISTOL ABOVE YOUR BELT. Repeat the drill SLOWLY increasing the speed. Again...keep the pistol below your waist. Learn to keep your elbow close & tight to your body and rotate the pistol upward to the target.
I think you'll be surprised at how quickly you can pick out different spots with your eyes and HIT them accurately.
I realize ammo is expensive, so you might want to consider trying my personal practice method:
It doesn't matter if you have kids, pets, wife...they all respond similarly to small squirt guns. The best are cats although grandkids are a close second.
