Is there any strength difference between older and newer 686's? What updated have been done to the 686 over the years? Thanks for the help!

There have been some machining changes, but the major changes are the use of MIM parts, the frame mounted firing pin,  and the locking safety feature of the most recent guns.  I don't believe the frame strength has been an issue with any of the "generational" changes.

I prefer the old ones...

I think Sheldon hit the high points for ya. I prefer my guns not to have keyholes and locks in the sideplates so, I buy older. I don't think quality has dropped appreciably so, I'd say it's mainly asthetics.

Thanks guys!

What are MIM parts and are they a good improvment or not?

I'm unaware of any MIM parts in a S&W, personally. Might call S&W & ask them??????

The power port on the newer (7 years maybe?) ones works great.

The newer revolvers have MIM hammers and triggers....possibly internals as well.  MIM stands for metal injected machining.  


A powderized metal is combined with a bonding material and is made into a putty of sorts and then injected into a mold of the part being made,  Once that hardens they heat the part up till the binding material is burned off and the powdered metal fuses solid.  At least, something along those lines.  It makes it cheaper to make a part.  I think most prefer the older forged metal parts.  I have not heard too many bad things said about the S&W MIM parts other than some saying the trigger jobs on the forged parts feel better.

smith-wessonforum.com/eve is a great site for S&W questions.
