I was wondering which years the S&W 686-4 (Plus) were produced. Also, was anything changed from the 686-3 to the 686-4?
Thanks!

I got this from a buddy a while ago. (edited out his and my comments)

"OK! Here's the skinny on the different 686 dash models from the Standard Catalog of Smith & Wesson, 3rd Edition, page 271:

686 no dash (1980): regular production started
686-1 (1986): radius stud package, floating hand (Don't ask me what that means.)
686-2 (1987): change hammer nose, bushing and associated parts
686-3 (1988): new yoke retention system
686-4 (1993): Change rear sight leaf, drill and tap frame, change extractor, introduce Hogue grips
686-5 (1997): Change frame design to eliminate cylinder stop stud, eliminate serrated tangs, change to MIM hammer with floating firing pin, change to MIM trigger, change internal lockwork
686-6 (2001): Internal hammer and trigger key lock
686-7 (2002): Performance center version in .38 Super Automatic

I don't have any info beyond that point. Hope this is the kind of thing you were looking for."

Since 1980 (older than me!)

Here is a run down from google search:
686 ''dash nothing'' - 1980

686-1, 1986 - radius stud package and floating hand

686-M - 1987 recall stamping on earlier versions

686-2, 1987, hammer nose change, bushing and ***'d parts

686-3, 1988, new yoke retention system
1990 - 2 1/2" barrel introduced.

686-4 ........ 1994 thru 1998 - many changes including move to 7 shot, sight changes etc.

686-5 MIM parts and frame mounted firing pin.


Someone else said this though.
686-1, is the same as the no dash except for a modification to the cylinder transport arm

686-2, no more firing pin on hammer

686-3, cylinder arm adjusted

686-4, rear sight changed, changes made to ejector star, hogue rubber monogrip becomes standard

686-5, internal lock introduced


I'm not sure which is accurate with regards to the firing pin location, but this was some quick googling to give you an idea. These are just other posters posts copied here.

The Wikipedia entry is also pretty good:

Sorry, wish I knew more about them

ETA: The post above mine looks more accurate. haha.

My -2 has a firing pin on the hammer... Weird. Inconsistancies in all these 3 lists.

Any idea what the recall on the -1's are (-M mark)?

Some of the no-dash and -1 models had an oversize firing pin hole. With some 357 ammunition, typically high velocity and light bullet combined with a soft primer, the primer would flow back into into the hole causing a jam. The -m indicates that the factory replaced the bushing.

I have a 586 no dash that jams with high velocity 357. Does anyone know where I can purchase the bearing so I don't have to send it in?

I'm pretty sure you need to send it in to the factory for the modification. Another thing I didn't see in the lists is around the -4 or -5 (early 90s) series they went to round butts only.

A lot of people think the -4 is the model to get. It has all the reliability updates and the drilled and tapped frame and non MIM parts.
