I'm not interested in 357 Sig, my interest is in the 9x23 Win in a 2011. I know they used to make them, but I cannot figure out why they stopped, as the 9x23 Win seems like a much better way to create a fast nine over the 357 Sig.
The 9x23 and similar were developed as a competition/gaming cartridge. The push was for a cartridge that made Major and created enough combustion gas to take full advantage of a compensator. The 9x18, .38 Super, etc. loaded to Major created pressure problems. IPSC lowered the Major threshold from 175 to 165 which put the 9x18 and Super back in the game and effectively killed the 9x23.
