I like my Hunter as well. I like it a lot. Like most Performance Center offerings, it is super accurate.
Though I have my eyes open for his bigger brother, I know the odds are slim, but one can hope.
Unlike Smithnut's version, my 627 Hunter came with an unfluted cylinder. I think we covered this some time ago that they were runs for different distributors.
I fell in love with the 8 shot concept back in 1997 when Lew Horton first announced the limited Performance Center run of only 300 pieces. I like serial numbers and really wanted #357 (bore diameter is an ongoing theme in my safe). Well I had to settle for #27 (top left of photo).
When Horton announced the second run of 300 pieces, they shipped me #357 (top right of above photo).
I am going to include the carbon steel, 8 shot, model 27s that were first introduced in 2000. I know you said 627s, but they are 8 shot. Obviously the middle guns in the photograph are the carbon steel variants. 4" and 6 1/2" were released as Bangor's Exclusives. 3 1/2" and 5" were supposed to follow the next year but never did. So there was just the one 5" prototype that was built in 1999 all by his lonesome.
It was not until 2007 when Lew Horton brought out the Registered Magnums that the additional barrel lengths were offered (blue and nickel).
Then there are the lightweight Scandium 327s. The 327 Carry and 327JM. I have not photographed my 327NG yet.
