Yes they did, but they're as rare as the 15", which they also made. I saw a 15" at a gun show many years ago and the 4" came up on auction a few times on Ebay, when they allowed them. The price for the 4" always went beyond what I considered reasonable. They were in the Norwich offering, before CZ took over and they may still have them in stock. I currently have the 9 1/2", two in 8" and a 6" barrels for my set.
