That was my belief until a few years ago. 30 some years ago a young guy hung around the local gun shop and he shot a .357M with 2 hands and he thought he was good but I would tell him that a pistol only had one handle and quit using 2 hands. He challenged me one day and I happened to have a Ruger Blackhawk 7 1/2 in. The load was a 240 gr. bullet and 22 grs. of 2400. He shot with 2 hands and I shot with one and wore him out. Time has changed things. At 79, stove up, crippled, weak and plumb wore out I now use 2 hands. Larry
