Yes, perfectly normal.
And, though it might not be the first thing to cross your mind when selecting a revolver for concealed carry, in some admittedly special circumstances the rattling rounds can serve as an unwanted "tell" that you're carrying.
The only circumstance with which I've personal experience is with a 340PD in an ankle holster. Believe it or not, in a quiet house, the rattling noise as you go up and down stairs seems quite loud, though I think most people likely would not pick up on it. Doesn't worry me, because there are practically no public places (maybe a library) that have so little ambient noise that the rattling would be easily audible.
Walking on a level surface is completely silent, of course.
