I think it should be pretty good - it's a .30 caliber round moving at peak velocities for a handgun - momentum is about the same as a 9mm round, with significantly less frontal area, so the penetration abilities sure make sense. I believe recoil should be about equal to that in a 9mm.

Nevertheless, unless you want it because it's interesting/different, the question is, would it really work better than the more common (ie available, tried and true (in the West)) 9mm/40S&W/45ACP/357Mag? Either a 9mm+P/147gr or a 357Mag 158gr+ can do some penetrating too if that's what you're after.

To me the main issues are that it is uncommon, and kind of an unknown, little supported in the West. On the surface at least, it sounds like a pretty good round on a ballistic basis.
