I'm glad that CZ has plans for a .40. 9mm is good and hi-capacity 9mm is better, but hi-capacity .40 is definitely more better. The .40 will truly be at home in the 41 oz SP-01.
Hopefully, the .40 will come out in a customized model with all the fixin's, like the Shadow. I'll be in line for two, once the design mods have been tweaked.
The only specs I could suggest for a new .40 SP-01 are a slightly shortened dust cover like the 75 Combat II, standard tritium sights, lower paddle thumb safety levers like the 75 SA and TS, and a firing pin stop without firing pin safety like the 85 Combat. Then it would be purrrfect.
