I have and use both. The 627 5inch is a bit faster handling, but the 929 with the 6.5 barrel is more accurate for longer shots. With either one to have a good smooth trigger you will probably have to reload your ammo and run federal primers after you work the action over for a lighter pull. Something on the plus side for the 929 is that federal has a commercial 147 grain coated ammo available that will work really well with light triggers if you do not reload.
One drawback with the 929 is that some moon clips do not go all the way in without a forceful push, and sometimes when they do go in easily they are hard to extract. I’m not sure if that is due to some bending of the clip through inexperienced use or not.
One thing that I found was until I had tried and used all of the brass I was reloading for the 929 and kept them separate I would notice that sticky case ,hard to insert/hard to extract problem and I found that the major reason for it in my experience was for a lack of a better term "glock bulged" brass. Once all swelled brass was replaced I no longer had that problemA fellow shooter (female) just bought a 929 as an upgrade to her 686-4 AFS. She had extreme difficulty with the trigger out of the box.
I changed the factory trigger rebound spring to a 14 Ib spare I had in my shooting box. The result was a much smoother and lighter trigger with no alteration to the mainspring impact force, therefore no lightening of primer impact.
The 929 came with a factory fitted ribbed power mainspring which was the only other alteration I would have made.

There are only 5 targets for steel challenge, there is no power factor, they are pretty big & close. If you don't/can't hit 5 in a row, you will likely lose anyway. IMO. Nothing very special needed. A 38 model 10 or 681 work fine for me.![]()
The only 627s that I know of that are NOT cut for moonclips are the early 6 shot ones, and there may be others I'm not aware of, but I think that any recent 627 8 shot is cut for moons.Which 627 are you looking at? I was deciding between the 929 and the 5" 627 PC and chose the 929. I chose the 929 because I already have a variety of older 6 shot 38 Specials and .357 Magnums and wanted something different.
Another consideration for me was that the 5" 627 isn't cut for moonclips anymore and I wanted something I could easily reload at the range.
The guns are very similar with more similarities than differences. It kind of comes down to what exactly you are looking for.
FWIW if you reload the cost between the 2 rounds is pretty much the same. If you don't reload the cost favors 9mm, however there is a much more diverse selection of .38 Special and .357 Magnum rounds out there where 9mm is much more limited. Light .38 loads will be lighter than the lightest 9mm loads out there and hot .357 Magnum loads will be hotter than the hottest 9mm out there.

When I had my 929, had a few sticky extracts at first. I started using all Winchester brass and never noticed the problem after that.
( I'm not sure why? but it seemed to solve the problem.)
I also noticed a bit of bullet 'jump' with plated bullets. Increased the taper crimp by .001 -.002 and also started using coated bullets and noticed less or no bullet jump.
