The 627 Pro has a two piece barrel!? I never realized that until I saw these pics of the muzzle. My 627-5 has a one piece barrel and I just assumed they were all like mine.

My -5 has a round barrel and it actually fits in the Kramer horsehide holster that was made for the Mountain Guns. I was going to suggest this holster for you Pro owners but after looking closely at your tapered lug I don't think it will work.

Regarding grips, mine is comfortable with JM grips and full power .357 Magnum loads. Getting mine all outfitted was very inexpensive. Another shooter hated his JM grips so much that he gave them to me for free. And another shooter had sold his Mountain Gun and was selling his already broken in Kramer holster for $20. I was delighted to find that whatever he did to break in that holster, it now fits my -5 perfectly.
