My local pusher, Southeastern Guns in Birmingham area, has had no trouble keeping both the 4" & 6" current production 617s in stock. I believe the ones he now has are $729 - but it'll be the 12th or later before they'll be back from vacation! Below is mine - bought new 9/08. I swapped the grips (Ahrends Retro Targets), front sight (HiViz), and springs (Wolff trigger & hammer - with adjustable strain screw), and a DS-10 speedloader and 6 x 10 plate:
Obviously, being a current production 617 doesn't bother me... having waited so long to get one, does! The are fun!!
