First, make sure the gun fits your hand. Find a set of grips that accomplishes that. Second, J frames can be very ammo sensitive. For me, 158 grain bullets shoot to point of aim, and 130 grain bullets shoot drastically low. Third, pay really close attention to marksmanship fundamentals. Small errors are greatly magnified by the short barrel and small size of the gun. One thing I have found with J frames is that if I use the highest hold possible, my trigger finger enters the trigger guard at a downward angle, which makes a straight back trigger press difficult. Accuracy improves for me if I grip the gun so that my trigger finger enters the trigger guard level, which necessitates a bit lower hold on the gun. The specific mechanics of what will work will vary depending on the person and how the gun fits your hand, but experiment until you find what works. If you pay attention to the fundamentals and work out a proper grip, stance, sight picture, trigger pull, pay attention to your breathing, and focus intensely on the front sight, if your ammo shoots to poa with your gun, you'll work it out.
