Never had a revolver but have a PT92 (Beretta 92 type 9mm) and have been quite satisifed with it. It seems however to have the opposite problem: the trigger pull, especially in double action, is quite stout.

As far as light action goes, Bob Munden the quick shot artist and gunsmith used to give free shows in my town and he had on display a S&W Model 29 he had worked the trigger on. I never saw a lighter trigger on a revolver but he swore it went "bang" every time on all brands he'd tried.
