Motored responce training
You might like to try a training technique to help develop motored responce.
Hold on aim, concentrate on sight picture, and with the trigger uncocked continualy and repeatedly take the trigger. The first objective is to demonstrate to yourself that you can take the trigger with out unduly moving the gun. If you can't, then return to just sitting, no aim, with the pistol rested in your lap, on dry or uncocked and practice the controled movement.
If you can hold reasonably still when its taken, continue, you must concentrate on the sight picture, and continue repeatedly taking the uncocked trigger, you should get 6 to 8 in sensible hold, but this time say "ten" to yourself when it is on the ten. One a hold is enough, more is better, none is back to holding and stability exercises.
The next step should happen subconsciously, continue with the cocentration on the sight picture and the same with repeated uncocked trigger takes, and say ten when it is, what will happen is you will gradually find that you will subconciously stop the repeated trigger takes and only take it on a ten. That is the brain taking over the action in responce to the sight picture. You are now on the way to a motored responce. The more work you put into it, the better the result.
Have Fun, and good shooting.
