My neighbor was in my shop after dinner tonight. He has a key and is reloading his heart out on my LnL. I needed to check to see if he was doing OK, and he was.
Sitting on the bench was a brand new 6" 617. Unfired. He wondered if I still had that extra Wolff spring set I'd bought and if we could install it. We could.
Popped the side plate and removed the hammer and trigger. Pulled the rebound spring slide. Had him polish that on an Arkansas stone while I put a polish on some of the hammer and trigger spots. I left the sear alone as he had no idea how it was shooting, and I'm not real keen on fooling with that. I also hit the inside of the frame with 600 wet/dry sandpaper. 14 pound rebound spring, full power main spring, stoned, polished, lubed and reassembled. In about an hour. Very sweet D/A, delightful S/A.
I have the 4", and prefer it for balance. He likes the 6" for sight picture.
He'll be putting Ahrends retro combat grips on it in the near future.
