It's apparently still offered. I've had that done to three of my 4" S&Ws, a 10-8, a 681-2 and a 22-4. It's a good value. The guns came back with a smoother and slightly lighter DA, a well-done bead blast (except the 22-4, which didn't need refinishing), and other specs where they should be. My only regret is that I didn't have the 10-8 and 681-2 made DAO. The 10-8 was my carry/IDPA gun until I went back to bottomfeeders.
