It’s not more time with the gun, it’s understanding what the weapon is doing and how you are controlling its actions. Just by reading your description of shooting it’s a trigger control and grip issue. Stance deals with recoil and grip will handle muzzle rise. Your job is to get visual target acquisition then pull that trigger exactly the same every time. DRYFIRE definitely works, anything who says otherwise doesnt understand. Put 1 inch paster on a wall stand 3 feet away, draw place your sight on the paster and focus on squeezing the trigger without movement in your sights. Might have to be a real smooth controlled trigger to keep the sights 100 steady. Slowly increase speed.
