I'm sort of a history buff and the use of two hands to steady a pistol is as old as the pistol itself BUT it was historically done when the distance was long and time allowed and often from a protected position.
Some thoughts...........
I am always shocked at the number of law enforcement officers shot or killed by drug crazed punks. Off hand you would think a police officer- well trained- would win every fight. The sad truth is whoever gets off the first shot has a bullet speeding through the air and that bullet has to go some place- sometimes with sad results.
The range I shoot at is a police range open to the public at certain times. I usually like to strike up some talk with the officers that might show up.
"Are you right handed?" I ask.
"Yes."
"Try some left handed shooting."
"Why?"
"Well...what happens if you get shot in the right arm? What will you do in a building if available cover requires left handed shooting?"
In any event I have often wondered if training forces you to do something you would naturally NOT do- like taking time to use a two hand hold when shooting from the hip or one handed might be the instinctive choice.
The same can be said of hunting. About a year ago on another forum a guy was crying because he lost a cow elk on an easy 25 yard shot. He hit it in the lungs but the hit was high or -whatever- in any event the elk took off and he never found it.
"Why the lung shot?" I asked.
"What else???" came the reply.
"It was a COW- why not shoot it in the head?"
Oh boy- what a stir that caused with all the tree stand hunters with their beans field rifles. I was accused of being unsporting, destroying a beautiful game animal, you name it.
I opined that we all read the magazines and all the guys in the magazines take a lung shot so....that's what everyone does.
Still more complaints- small target- unsporting, etc, etc.
Now on a baseball diamond it's 90 feet from third base to home plate. If someone can't make a head shot at 25 yards with a RIFLE they have no business being in the woods.
In any event- go head and practice the 2 hand hold but do some old time pistol shooting as well. Put some candy wafers or crackers in a crack in a log and shoot them off hand- ONLY HITS COUNT. Make that tin can dance and shoot fast while its still moving. Practice with both hands.
Once you become a talented and fast shot one more thing is required.

and be polite when all the two hand only crowd tells you that you're not doing it "right"
