How much trouble is it, to replace the thin factory hammer, on my 686-4? I'd like to replace it with the wider, target hammer.

Not hard if you are familiar with the internal parts and how to remove them. It would be about a 10 minute job unless stoning of parts is necessary.

I've done it. No problem at all.

I feel very comfortable with the removal, as well as the reassembly. My concern is the fitting of the parts.
What are the chances of ordering a .500 width hammer off of Numrich, and having it just drop in and work like it's supposed to?
I think chances are good it would work fine. Just make sure the hammer is from the correct era.
I've done that same swap on a 686-4, but there was some fitting that needed to be done. The hammer I got from Numrich had a DA sear installed; however, it was too long to function properly. Since I didn't want to try and fit it, I took the DA sear out of my original hammer and installed it in the target hammer. Dropped right in after that and functioned perfectly.
As noted, replace the sear instead of cutting a new one. The correct process can be tricky.

The problem is more likely finding a case hardened L frame target hammer. The correct one would have a silver hammer nose. The only one I've ever seen is on my 686-4 8 3/8s.
You could find one from a 586 but the nose will likely be blued. Also if it's a pre M stamp nose it might not function correctly. I couldn't tell you the difference by looking at them

I found one at Numrich, that's supposed to fit. Don't know how correct it is. But my 686 is just a shooter, so if it works I'll be happy. If all goes well, I'll be looking at swapping the trigger next.
