I have a Model 16-4, rechambered by Bowens to 327 Federal Magnum in 4" blue. It is a fantastic revolver. So I have one, and the new chambers have no effect on accuracy with the .32 Long wadcutters I use in my Pardini (either my handholds or Fiocchi commercial). Why a new gun. With the 327 Federal, a ported gun will be back on target faster. SS will be easier to clean.....All the benefits of a .32 Combat Masterpiece and more....
