FWIW-
It appears the Mod 66 and Mod 69 have now been moved to the K/L frame section-
Product: Model 66
It also appears to me that they MAY have simply altered some old, existing copy for another page instead of starting from scratch, and that is why it says "Two Piece Barrel". I do not believe it has a two piece barrel. It also says "• Full Top Strap and Barrel Serration ", and I believe that is also leftover from the old copy about another gun. If you watch the video, at 0.29-0.31 the top of the gun is clearly visible, and it is NOT serrated.
It DOES have the ball detent, or at least it is obvious the forward locking bolt is not in the shroud.
The above is my observations and opinion.

Below are the Facts of Life-
Man, the haters are out in full force here!! Can't these people get over something that happened almost 15 yrs. ago? Why do they keep posting their venom in threads like these? If you don't like S&W's new models fine, but don't stop & piss in every thread like some drunken brother in law at Christmas! This BS was old TEN YEARS ago. Get over it & move on. This is why S&W is making money & Colt has had the wolf at the door since '86. Technology changes and people do as well or they get left behind.
Eloquence, sheer eloquence.

Really- well said.
I invite you all to read this sticky, particularly
Post #66:
Sticky: LOCK- ..can't get past "the hole".
Some of you should read it two or three times.
If you want to coo and cuddle about vintage revolvers made the old way, there are three forums above this one for that purpose. Go to one and have at it. Enjoy yourself. Meanwhile, let people who buy/shoot/own/collect the current production products enjoy themselves.
All the bitching and moaning accomplishes nothing, and actually lowers the usefulness of this board.
Think about that- a newbie to guns has heard that he/she should start with a revolver, and hears S&W recommended. The newb comes here to find out what new gun to buy, since he/she knows NOTHING about them. They get pummeled with rants that new guns are junk, and they should buy an old gun. Now, remember, this person knows little or nothing about guns and needs advice to sort out the new guns as far as size, caliber, and style, and finds the subject almost overwhelming, and you just said "Go buy a used gun". Do you really think you helped them?
So, here is how it will work-
If you'd like to enjoy/love on/cuddle/read about/post pics of/whatever the older guns, go to the three vintage forums and have a good time.
If you'd like to enjoy the post 1980 and current production guns, this is the place!
If you'd like to rant/rave/bitch/moan/whine/cry in every thread started in this section and discourage new gun owners and shooters, GO SOMEWHERE ELSE. I mean that. If the inability to rant/rave/bitch/moan/whine/cry incessantly makes this board unusable for you, find someplace you like better. You ain't wearing chains.
We might all be better for it. 
I hope that is clear.
I'm sorry to be so negative in my posts about current production Smith & Wesson revolvers but the ONLY way to motivate any company to change its product is to let them know the current item is not well-liked.
You do know that S&W does not own this board, nor have any affiliation with it whatsoever, don't you?
You do know that we don't make the guns here, don't you?
I would suggest communicating your opinions and desires directly to S&W. All their contact data can be found on their website at
