Gang I phoned Ruger the other day and explained to the girl on the phone. She said she'll send me new grips to try. So I'll have two, and will keep the ones that fit and look best on my revolver and sell the other one. If they're loose too, I might try a bedding compound or the likes thereof. Might just be my particular grip frame.
Regardless, I'm warming back up to the gun. I re-measured the cylinder gap and it's actually .004", perfect. Timing and lock up are so good, with just the tiniest amount of endshake which I understand all GP100s should have for proper function.The gold bead still isn't my favorite but it now has a satin sheen thanks to hitting it with an Arkansas stone and that makes it look much more even in different lighting conditions, before it was hard to pick up. I highly recommend doing that.
The trigger pull isn't as good as on my S&W Model 66, but hey, that's an old world Smith that's probably smoothed from use.
Will keep you all updated!
