460 rowland is NO joke. Its a modification kit for the 1911 pistol, basically its just a new barrel with compensator and recoil spring.
The cartridge is merely a slightly enlongated .45acp, with much thicker brass to handle the higher pressures. I have seen .460 rowland loads capable of nearly 1800 fps using a 185gr bullet out of a 5" barrel.
Depending on the strength of the recoil spring used, standard .45acp ammo can be fired out of a .460 chambered gun with no problems.
So as you can see the .460 offers many advantages in a belt gun sized 1911.
The 356TSW is basically the same concept as the 460. That is, a slightly enlongated 9mm loaded to higher pressures.
