I practice all the time with my air pistol Walther P99, I already had a good trigger finger control and muzzle control, but it has became second nature, even if it is not a real firearm, my finger is never in the trigger guard and I always point it to the floor or is someone is in front of me, to the floor at my left/right.
Be sure to know that your fingers go where your brain wants them to go, your trigger finger will never go in the trigger guard or worst on the trigger if you have good control of yourself (I hope you can control your hands.... lol).
I'll pass my CFSC (with the course) in two weeks, no worries about that one, november 8th, then the hunting initiation with firarms course the 15th, then the CRFSC with the course, I don't know when, I'll have to call fo that.
