I may be mistaken, but the newest two peice barrel 67s are the dash 6 models - Craig Buckland is using them to dominate the SSR division in IDPA. S&W has gone back to the one piece barrel this past summer and I think those are dash 7s. The revo pictured with the failure is a dash 5 - could it be that S&W is trying to recycle some of thier old stock? Those guns may be new to the users, but they aren't current manufacture.
