Get a used gun (not abused, but realiable)...see if any local fellow shooters will let you borrow and try their limited guns, and see if you like a particular gun, setup, etc.
Maybe you are prepping your trigger (like on a 2-stage trigger system)?.....and yup, dry fire, and learn how your trigger behaves and trigger control. As you may already know, the lighter the trigger, the more sensitive it is.
