Not so far as I'm aware, just 2" and 4" versions, but I'm often surprised to learn of oddball runs for distributors such as Lew Horton. In my limited experience, I thought the 2" sight radius was inadequate for adequately accurate aiming ... I looked at one of the new 5" 63's the other day, and it's really sweet, but my 10 round 617 is sweeter!
