Without being there to see and hear what you're talking about, I'm pretty sure what you're hearing is the hammer block moving up and down in its recess. If you had a modern hammerless S&W revolver you could check (they're not used on modern hammerless revolvers).

Regards,

Dave

PS - Sorry, I should add that if it is indeed the hammer block, there's nothing to worry about as it is functioning as it should.
