I don't have a 351C yet, but I giggle every time I pull the trigger on my 43C -- too much fun. I shoot about 95 percent in DA mode, even with SA guns, so I don't notice a heavy trigger. I'd say my 43C is probably a bit lighter than my .38 or .357 or 9mm Centennials.

I think it's impossible to say every 43C is lighter than every 351C. I believe each undoctored revolver has its very own pull, no matter the caliber, and they all seem to improve with use.
