RE: Need advice
It's easier to train the non-dominant hand to draw the string or manipulate thebolt/safety/slide/triggerthan it is to train the off eye to aim where thedominant eye is looking.
It feels darned unpleasant, awkward and clumsy at first, making the 'wrong' hand do the work but, if he'll just gut it out and stick with it,that feeling goes away. Sometimes it takes several days to a week or two, but it'll go away.
