Updated revolver
Can S&W update with newest or even some modifications. I am thinking of buying a 649 no dash and think that some of the modifications can be applied to existing frame. Such as new yoke screw, new yoke and so on.
Not sure they will do the work so asking the experts.

Why would you want to do this? I’m not being combative. I’m genuinely interested.

They won't alter an old frame.

As an old S&W Armorer I know the changes made on Smith's were much needed and enhanced the operation and longevity of the product. Did a lot of hand fitting on the old style revolvers and upkeep was labor intensive. And of course spares are not to be found these days.

Having carried and practiced with a 649 no-dash for years, I rate it highly without modifications needed. But, I am open to learning; what changes would you desire, and for what reason? What could they bring to my table that I am unaware of? Genuinely curious.

If you own a vintage revolver that is out of production I would NOT send it to the factory.
The craftsmen who built it don't work there anymore.
Find you a good revolver smith instead.
Just my 2 centavos worth.

The yoke button was replaced with a shape that let the yoke screw adjust automatically for yoke shake. The cylinder placed a raised ring to help keep expanded gases out of the area the cylinder rides on. A raised shoulder was put on the trigger studs and hammer stud to allow them to ride free of the frame and prevent dirty areas under the side plate binding the trigger or hammer.
I still have my tools I got in the Armorer school but even with them parts will be needed to repair all sorts of problems caused by wear and tear.

There has been a boss on the hammer and trigger studs forever, The nev style taper and ball type yoke screw is NOT as robust as the old style. Report of cylinders and yokes falling off out of the gun during reloads have occurred with new style. A new screw and peening the yoke button is easy and seldom needs done. I have never had problems with the old style gas rig and have ran guns to high round count without cleaning with no problems. I think your looking to fix what isn't broken. I am not against the new guns, and have 5 of the scandium models and a variety of them with MIM parts. They all work fine and have never failed me. But, I hardly think they are in anyway better or more durable than my older guns.

The new yoke screw is a larger diameter thread and will require a bigger hole to be drilled and tapped.
However S&W will not do any modifications except what they do on new guns in the custom shop.
S&W will not even take in a gun w/o a Model stamped on it; guns older than 1958.
A good discussion of the new guns advantages, Model 19:
