I am in agreement, this is the version S&W should be offering for sale. The 3 Inch barrel L Frame is about all the revolver I can conceal carry year round. Barrels longer than 3 Inch block access to my Right back pocket, where I carry my Bill Fold.
I also like to carry reloads. With a 7 shooter you are limited to the HKS 587 or a 5 Star. With a 6 Shooter you have the choice of a Safariland Comp II or Comp III, as well as the L Frame Jet Loader. All of which are faster to operate than a Turn Knob speedloader.
Next issue is shooting your concealed carry revolver in a match. IDPA SSR Division, and ICORE Classic both limit the round count to 6.
I gave up on locating a reasonably priced 3 Inch 686, and instead picked up a 3" Willy Clapp GP100. It is a 6 shooter, and not a collectors piece like a CS1.
