Why S&W has never come out with a 10mm L-frame is quite the mystery. They did the big N-frame in 10mm and the 646 L-frame in 40S&W but the 646 used a titanium cylinder. Had they used a stainless-steel cylinder it would have been so easy to have made/converted that to 10mm Auto. A fixed-sight, 4-inch, L-frame in 10mm Auto would be a combat revolver beyond compare.
