No I am talking 15 yards. I can shoot a revolver or a glock type auto pistol, dead on with my strong hand. That's the way we learned 45 years ago. I can shoot almost as good with my weak hand at 7 yard distances. Been doing this a long time, and practice one handed shooting every time I go to the range.
You may not have time to get a grip on the gun with both hands, fast drawing out of a holster, with someone off to your side. Turning your body will take longer than pointing your arm.
Be glad to show you if you get up my way.
Sometimes you only get to use one hand, you may be shot in the other, my advise is, if you don't spend 10 minutes every time you train, you aren't maximizing your time. Shoot with either hand until it just becomes second nature, the 2 handed shooting position is fairly new, as gunfighters and soldiers up until the 50's or 60's.
In Mythbusters, there is an episode in which they compared many firing stances, including having a gun in each hand and found that, compared to the two-handed single gun stance as a benchmark, only the one handed shoulder level stance with a single gun was comparable in terms of accuracy and speed. The ability to look down the sights of the gun was given as the main reason for this.[7] In an episode the following year, they compared holding two guns and firing simultaneously—rather than alternating left and right shots— with holding one gun in the two-handed stance, and found that the results were in favor of using two guns and firing simultaneously.[8]
