A pistol round that will make many people happy.

I disagree. Starting diameter is only slightly smaller than 9mm and it's possible to get .50 cal expansion or larger. What you say would be true if you're limited to FMJ ammo, in which case, it'd be inefficient as a man stopper. (probably comparable 7.92x33Kurtz, 7.62x25 tokarev and .30 carbine with ball ammo) But in a case where you'd need penetration, it'd have plenty of it.
With expanding ammo, wounding should be significant. If you don't think a .308 cal bullet at ~1800FPS can't do significant damage, talk to the hunters using .30-30 at 100-200 yards. While .30-30 bullets do tend to be heavier, impact velocities at common hunting ranges will be comparable to impact velocities and energy levels at SD distances with the .308-10mm

With lighter bullets intended for 7.62x25 tokarev, as Ballardw suggested before, rifle like velocities could be attained, likely at the cost of soft tissue penetration, with an expanding bullet. Which could be desirable, if you're intending to create maximize temporary cavity size.
 
If it expands up to .50, you're saying that it is the lethal equivalent of an unexpanded .45 ACP. Except that it creates a smaller entry wound, and it's depth of penetration is either the same or less than .45 FMJ.

How great does that sound?


And that's only if you can come up with a bullet design that will reliably expand at those velocities without fragmenting. With half the starting frontal area of a .45 and 72% the frontal area of 9mm, you have much less hydraulic area to expand the bullet. This is velocity range is another limbo, between where traditional pistol hollowpoints become either too fragile or under penetrate, and rifle velocities and weights where you switch over to tougher spitzers and soft points.

If you go down to smaller bullets, you can more predictably get them to tumble. But a .30 bullet at these velocities isn't going to expand much and is too heavy to yaw much either.
