A first time gun owner, I would get his hands on as many different guns as possible, and encourage him to study the different guns and chamberings.
My wife stated out with several friends bringing out guns that they had, and she shot quite a few of them. After that, we went to a gun store, and she made the choice on her own.
She had that pistol for about a month when she decided that she wanted something smaller, and in a bit heavier chamber. Hopefully with as much exposure as possible, and a bit of research on his part, and he can avoid this issue.
