Before you move to any other form of pistol shooting, you need the fundamentals.
Marksmanship Fundamentals are critical to any shooting, be it pistol, rifle, action, or target shooting.
I would highly recommend you pick up a copy of the Army Marksmanship Unit's "Service Pistol Guide".
It only cost $6.95 from the Civilian Marksmanship Program (CMP).

Once you have marksmanship fundamentals down, then you can that that and apply it to any and all forms of Pistol/Revolver Shooting.
