No. They have a shorter sight radius than longer barrels that, in general, makes them harder to shoot accurately. If we were to mount two Smith & Wesson .38 Special revolvers, a six inch and a two inch, in a machine rest, both would very likely display about the same level of accuracy. However, if you were to try shooting both from a typical unsupported stance, you would probably believe that the longer barrel was more accurate. Its longer sight radius makes it easier to achieve and maintain proper sight alignment.
