I have both a 686 and a 629 Competitor. The 686 was converted to 7 shot, cut for moonclips, had an Apex trigger job done, and I put a Delta Point on it. Great gun I like it a lot, and have shot a lot of local matches with it! I have no issues at all.
The 629 is stock other than cut for moonclips. Shot that in a match last weekend.
Owned this one for some time til a good friend talked me out of it a half dozen + years back.
The gun shot much better than I can, hope to get it back some day, but not holding my breath.
