A while back I was shooting a 1/2" aluminum plate at the range. My .45s were just making dents the size and depth of a dime in it. My Tokarev was blowing holes all the way through, with major spalling on the exit side.

It's only for 9mm or .38 Super M1911s (unless I'm reading it wrong.) 9mm is pretty cheap as is, even the non-corrosive stuff, so I don't think you'd save that much money. And while I know that .38 Super is popular with competitive shooters, how many .38 Super M1911s can there be out here?

Colt still makes them as do a few other 1911 makers. I have a RIA in .38 Super.

If the admittedly non-scientific-method of the Box of Truth can be trusted, 7.62 Tokarev has above average penetration, being capable of punching through a Kevlar helmet, something no other pistol rounds tried could do.

However, it doesn't necessarily carry a lot of stopping power, not to mention the testing was by no means exhaustive.
