The original guns were shipped with unfluted cylinders, as did the .41 and .44 UDR guns. That one apparently has had a trip back to the factory for a fluted cylinder. The gun used in the Bloodwork movie had a fluted cylinder. I much prefer the looks of a fluted cylinder. The grips on the bottom photo are what the guns originally shipped with. They feel small, but are nice for carry. The are manageable for combat use, carry a lot shoot little.
The last one I saw for sale was about $2000. One of our members, Silvercorvette, kept up to day on one he was bidding on a few short years back, that went for over $3000 as I recall.
By the way, where did the Silvercorvette disappear to?
Good luck on your quest for one of those beautiful 627s.
