I would suggest starting to work on left handed shooting. Get a toy gun to practice with. I am right handed. Left eye dominant. I shoot left handed for pistol, rifle, shotgun, and bow. I do handgun shooting with my right hand for practice in the event my shooting hand is unable to be used. If you practice it enough doing left handed becomes automatic, and your sighting for a flash sight picture will be faster.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
