IMHO no reason to redesign the wheel. S&W and many other very intelligent firearm designers/manufactures make these things handle the best they can considering what they do. IF a comp on a threaded ported barrel(if there is such a thing?) works better then each do individually, then I think smarter folks then me would have already figured this out.
