I bought a set of Ahrends unfinished cocobolo retro targets for my new 4" 617. I finished them with several applications of my homebrew penetrating oil/resin finish. I added a HiViz front sight and the 6 x 10 baseplate and speedloader from DS-10. Not seen - a lot of live-fire breakin and some spring changes, mainly a lighter rebound spring. Fun firearm!
Ahrends regular finish is 'brighter' - that is, it doesn't darken the ligher colors like an oil finish will. Here is my 627 Pro sporting standard factory finished Ahrends cocobolo retro targets:
I believe the Ahrends grips are still $60 + $6 s/h direct from them - and they work in an old fashioned way - they'll take your check! Nice folks.

PS While a 4" 617 is capable of some decent bullseye shooting - I'm a plinker. Break it in with Federal 36gr HP 550 packs from WallyWorls - or splorge with Federal Automatch... no need for expensive ammo. It has a beer palate - leave the champagne for bencgrest rifles!
