I recently got a 627 "pro". They also had the 627 V-comp, but it was $500 more.
I took it to my local smith, who builds race revolvers. He completely reworked the internals and smoothed everything out for me. I didn't have him take the trigger to competition level light as I wanted to run factory ammo through it.
I swapped the grips out to the smooth rubber Hogue (model 25012) so I could get rid of those awful finger grooves, and I popped on a Hi-Viz sight. Done.
The N-frame is a honey with .38 and still very manageable with .357. My first time out, I was able to keep a cylinder dump within a 6-7" circle from 7 yds back (I was screwing around to see if I could). The weight of the barrel on that pro model keeps the barrel hop way down, it is very manageable for followup shots.
Long story short? I'd save the $500, get the Pro, and have a smith rework the internals.
