Yes, the .45 ACP/50m effective range reference was from an SMG. Those big, fat 230gr FMJ's have hardly any penetration power as the distance increases as well. One cartridge that I really love that fits the PDW role extremely well is the 7.62x25. I've been wanting to build a 1911 in that cartridge for a while, but sourcing a mag for the 1911 frame that will fit the Tokarev cartridge's COAL is futile. There is a company offering a 1911 barrel chambered in 7.62x25, but it is non-ramped.
A highly-gifted gunsmith I know in North Carolina built an AR15 chambered in this cartridge. He used a blank lower forging, and broached the magwell to take Soviet PPS mags. He cut the rest of the lower to spec, and cut mag catch holes in the PPS mags so they would lock into the lower a la AR15 fashion. He made a barrel bushing for a PPSh pipe so it would slip into the upper, and you just hand-screwed a carbon fiber handguard onto it. A 9mm SMG bolt and SMG heavy buffer completed the rig. He baked-on some proprietary DuPont metal surface finish meant for chemical pipes, and it turned out really sweet. It would blow right through 1/4" steel plates within 25m.
I have done side-by-side comparisons of 9mm, .45 ACP, and 7.62x25 on a Finnish Army steel drum from WWII that was in need of being used as a burn barrel. The 9mm and .45 bounced off it repeatedly. The Cz52 chambered in 7.62x25 shot through one end and out the other, even when I shot deflecting aspect shots.
I also have friends who have shot amazing groups with a Tokarev or Cz52 pistol at 200m with iron sights. You used to be able to get a 1220rd case of it for $129, but I can't seem to find that anymore...word must have gotten out.
