If your cylinder is shorter you will have excessive loss of speed due to the cylinder being greater than the Factory .0006"... We tried this in the 1970s with our PPC 38 Specials machining the cylinders shorter so that the 148 gr HBWC would almost be flush and have less bullet jump to the forcing cone making better accuracy. It didn't work as we also had to turn down the 6" barrels, rethreading them to screw in further and keeping that .0006" gap.

Nope! But also remember the 9MM is a tapered case but not the 38SC so you may be able to ream your 929 cylinder but why?

When was the gun mfg? Older guns never had issues. Newer guns as mentioned above use MIM parts (metal injection molding or powdered metal)

9mm is a tapered case and the 327s & 627s are machined for straight wall cases...

I am certain that nobody has ever made full moon clips for a Colt as even the cylinder release is too slow for opening to reload...

Here is the parts number from Brownell's. I bought these a few years ago...

I always get my own brass back since its attached to the full moon clips. I have reloaded the 38 Colt short 25+ times with a small amount of split cases...

My Brownell's 38 Super full moon clips have fit all 5 of my 627s and cylinder closes as it should. Factory Starline 38 Super brass drops in with room to spare and ejects easily. Reloads must use the undersized 38 Super die that George makes at EGW. (Been doing this since 1997) However, I mainly shoot 38 Colt Short (with 3/4" of freebore) because of no advantage to shooting Major.

I shoot CCI 40 gr HPs, they are readily available and shoot very consistently.

Just buy the EGW unersized 38 Super die and re-size all your loaded ammo -or- buy new 38 Super Starline brass and load it. Both fit in ALL my 627 cylinders and extract easily.

Reaming of your 627 cyinder is not necessary to shoot 38 Super 'IF' you size them properly with the EGW undersized die (-.0002) or use new Starline Brass. I have Brownells 38 Super Full Moon Clips that work great with my Starline brass.

This would create another revolver division and we already are the smallest USPSA shooting division... Iron Sight (Ltd Revo) Optics (Open Revo)

In the 1st year of shooting my 627, I sent back one of my early 627s when Tom Kelly was the there for a broken trigger pin. The RA came right away and it only took 2 weeks to get it back. I still believe all warranty work requires the entire gun back.

Parts will not just drop in as you think. Be prepared to re-modify and re-smith many...

The 929 with MIM parts is way more expensive to tune that the older 627s with forged steel parts. Best to find an older 627 before they added the trigger lock system and MIM parts
