Sorry but I have to disagree you here. The reason that 38 Super and other hot 9mm ammo (longer cases) are popular with competition shooters is to make the major power factor of 165 or higher with a high round capacity gun, not to knock over steel targets. The steel targets are set to fall at the lowest power factor legal to use in the particular match. The reason these 9mm are popular is that they allow the shooter to reach the major power factor levels (often a scoring advantage over lower power factors) with the most rounds of ammo in the magazine. The restrictions on the magazines are by length and not capacity or anything else, so a magazine of max length can hold a lot more 9mm rounds than .40 or larger rounds. Fewer reloads means faster times!
The 9mm Luger can be loaded to major power factor levels, but it's very tough on the gun and can produce dangerous pressures, so most don't do it.
BTW, most action pistol competition is OC. Only IDPA requires concealment.
Just from what I have read here I believe a good number of 9mm cc and oc are using hot +P 9mm. Without penetration it boils down to kinetic energy and the 9mm has a slightly higher number. Still a mute point as the theater was a gun free zone.
