There has NEVER, I repeat NEVER been a single study, test, or any other documentation that shows 45 is any better than 9mm when using the same exact ammo. Compare FMJ vs FMJ or modern HP vs modern HP in 45 vs 9mm and every single one of them shows a tie.
Did ya miss the Thompson LeGarde test of 1904? Yeah, that's over a century ago, but when talking non-expanding bullets; nothing has changed since then and the test is just as relevant today as it was in 1904.
The .45 ACP does produce a larger wound; that's just physics.
Now the question I think you're getting at is; is it enough to make any practical difference? If that's your statement, than yeah, I don't know of any test that has shown that there's an actual difference in incapacitation. There was the "Strasbourg" tests, but they were in "secret" and the methods were not open to peer review, and thus cannot be taken as credible science.
BTW, I'm quite confident the "Strasbourg" tests were not in Strasbourg France, but in Texas.
