Default 686 dashes

I know the info is buried in here somewhere, but could anyone tell me what the difference is between a 686 no dash and a dash 1 ?
I saw a YouTube video and the guy said what all the dashes were, but I still don't know if they've were actually improvements or just a way to cheapen up the guns. I'm mainly interested in a no dash and a dash 1. But I'd love to have an explanation on dash 2 and 3 as well. Thank you

That's what the video mentioned....but on a dash 1, what is a radius stud package and a floating hand? Are these actually improvements? No one can tell me what they both do. I can't find that explanation anywhere.

It would be great to have a rundown of what all these changes (dashes) do. Where they really improvements or just a way to cheapen the cost? It would be so helpful for people to know. Thanks

The -1 is a different duck. Sorta.

Its virtually identical to a no dash. With minor work to the studs but introduced the "floating hand ".
I would only get a dash one if I knew it wasn't shot up alot. They did have problems. S&W was trying to simplify the building process with it and later dropped it.
A floating hand setup can be converted to a non floating hand. And both models are under the "M" recall also.

Not sure what the floating firing pin was supposed to do, but it seem to create a "hitch" in the double action trigger pull. Thankfully, it was replaced with the original design. I ditch all I find!!

Lou the welder, what issues did the -1 have? I just recently bought one. So far, everything about it is great, and I intend to keep it for life. Mine does have the "M" stamp.

My 686-1 has a hitch in the single action cocking motion towards the end. I thought of trying to install a non floating had but haven’t gotten around to it yet.

If it already has the "M" modification, you should be fine. The only other issue was the hand, but that isn't a big deal.
My 686-1 is a no "M", floating hand and i shot it DA on purpose. It did ok.

Without the modification "M", the revolver would purportedly lock up on certain type of ammo.

Thx. My -1 is one of the the smoothest revolvers I've ever shot in DA. GREAT SA trigger too. I dont know its Hx, but I bought ot at a pawn shop for $600. The owner said an 80 something yo man brought it in with a pump action 30-06 with a 70s scope. I thought about buying it too. I dont think either were shot for the last 20 years.

Before that, who knows.

My 686-4 6" bought new in 1994 still had the square butt frame and the original style cylinder release.

Also the 686-4s I've seen no longer have the flash chromed trigger/hammer and have the case hardened finish like the blued revolvers.
