I've shot lefthanded all my life. Because I started out shooting righthanded guns, I got used to the way right handed doubles open, and the firing sequence as it was. I have a few doubles that have been either restocked with left hand dimensions, or bent that way. The single time I tried a true lefthanded double, I was mystified as to how to get the thing open after the shot. It was not comfortable for me to use.
Just having the stock and the triggers bent is as much as I need to improve a guns handling for me. Of course, I have a few that are clearly right handed guns, and I still muddle through with them.
Good Luck with your son and his shooting.
Best,
Ted
