Call me old fashioned, traditionalist, or a throwback, but i think I like the first revolver pictured better. The bottom one is ok, but it looks like its one flashlight and bayonet short of being a tacti-cool revolver. I also don't care for the look of the good year all-weather radials on good revolvers.
It still a great gun either way though. I shot my friends DW 15 and it was accurate. They are nice guns. I actually want one for my collection.
