Hi rodfac,
For a brief period of time, the 10MM was all the rage. However, when science entered the duty gun equation, it was found to be true that .40 caliber handguns were most efficacious when firing 180 grain bullets at ~1000 FPS. Hence, double stack mags of very efficacious .40 S&W ammo supplanted single stack 10MM duty weapons.
Gun design has a huge impact on felt recoil.
