I was lucky enough to acquire a decent gun collection but I am completely new to revolvers. I’ve done my best to search on my own but there is a lot I don’t understand. A Reddit user pointed me here and I’m hoping you all can help shed some light on this!

What I know:
4” barrel

Behind the yoke-
A UN 6736 listed above model (transfer paperwork says this is the serial number but it isn’t located in either place the sticky thread said to find it)
586

On the yoke-
313
36398 or 3639B


Any additional information at all would be amazing, especially the year it was produced. Thank you!

The A run was from 1980 to 1986 if I’m not mistaken. Being a no dash, likely made from 83-86. But S&W admits they have large gaps in the serial number sequence. So it may be an earlier model. Hope this helps. Nice piece either way.
 
Welcome to the Forum

The official place for the serial number would be on the butt of the revolver.

When a revolver configuration gets grips that cover the official serial number, Smith and Wesson will place the serial number in a second location that can be viewed without using any tools. Most commonly that second location is behind the yoke

AUN6736 is the serial number of your revolver

An AUN prefixed serial number is most likely manufactured in 1987. If you would like to know the ship date of your revolver and who it was shipped to you need to request a historical letter.

The rear sight is a Millet rear sight replacement, not the original Smith & Wesson sight. That really makes little difference, or possibly an upgrade, for a shooting gun, but would be a detraction for a collector. Also, there is a recall on the 586 series guns from that era, where the hammer nose and the bushing is replaced. The issue was that some hot 125 grain .357 Magnum loads would lock up the gun. This only affected a small percentage of guns, but Smith made an update for them. I understand they will still pay shipping both ways to install the update. Many folks don't bother. You can test yours by shooting some 125 defense loads to see if the primer will flow back into the bushing, and lock it up. When the gun is updated, an M will be stamped right above the model number in the yoke cutout.

They are excellent guns, by the way and generally well made. You have a very nice one and will last a long time.

I'd recommend removing (carefully) the target stocks to verify that the serial number that should be on the butt has remained intact.
 
Again, welcome to the Forum! I responded to another of your Posts (Model 17-4), and it appears that you did acquire quite a nice collection of fine revolvers. The L-frame Model 586 (and its stainless steel cousin the Model 686) is very popular here on the Forum, and the early "no dash" revolvers are often the most desirable. As mentioned, your revolver was manufactured in 1986-1987, and appears to be in great condition. Don't be afraid to take it out and shoot .38 Specials or .357 Magnums, the L-frames are extremely robust revolvers. Enjoy!
 
Welcome to the FORUM from Michigan! You can learn many things here and drool over pics. I traded in to a 586 no dash some years back. (1983)Yours and mine don't have the M stamp (by the model#) which a recall being done. Also have a 5" 686 Pro Series, 7 shot. Bob
