DT,
I have had many revolvers over the decades that were purchased used and exhibited the same condition as yours. The usual culprit was someone doing a little too much stoning and filing on the hammers and trigger bars trying to get a very light pull. They sell the gun cheap thinking it was ruined, I buy a new hammer and rebound bar and good as new.

DT...Not sure if you know about this, but...relieve almost all of the tension on the mainspring before you remove the sideplate, and never EVER cycle the action with tension on the spring while the sideplate is off.

Hmmmm. My knowledge extends to a couple of manuals, the Kunnhausen book, and the AGI videos. I know the theory really well. The hands on often as not doesn't work out as well -- so I go very very slowly and stop when I get to something I don't understand. Appreciate the tip, JohnnyT.

Tips on source of supply for hammer and rebound bar for an old style Model 28? Didn't find any at Brownells or Midway -- and S&W only sells those to card-carrying armorers or gunsmiths. Probably for good reason.
Thanks
Dave

I'm going back years. I guess they stopped the practice now. We could buy all the parts we needed. If Brownells can't Help, maybe GunParts or Numrich Arms?

Can't beat that offer with a stick.

By the way...you can trust Wild Bill with your address, etc. He spent a couple weeks here about four years ago. Purty good Joe once ya get past the initial shock.

Updated Info & Photos of Sear & Hammer

I appreciate everyone's suggestions on this. I finally (!) had some time to seriously clean and check the Model 28. That almost made the single action hold, but push-off still takes about 1 pound. I think the sear is worn, but I don't have enough experience to judge. So, I got out my handy-dandy micro camera and took a bunch of pictures of the trigger assembly that show the SA notch and the hammer assembly showing the sear. It looks like honing the sear MIGHT solve the problem (if I don't destroy the trigger). AGI recommends not to ever touch the SA notch on the hammer, so I'll take that advice. If I screw up between Numrich and Brownells it looks like I can get a replacement hammer and trigger for about $100. Anyone have any final suggestions based on the photos before I get out a stone and vice and try the delicate work?
Here's the pics:
