The original 10mm load was a 200 grain bullet at 1,200fps from a 5" barrel. A 200 grain 10mm bullet has greater sectional density than a 230 grain .45ACP bullet and the 10mm is flatter shooting and penetrates deeper where the bullets are of equal construction.
The run of the mill retail stuff on the market today, unlike the .45ACP offerings, is loaded well below the SAAMI pressure spec established for the 10mm (37,500psi). The .45ACP is 21,000psi.
Double Tap ammunition company sells 10mm ammo that is much hotter yet still within SAAMI specs. One of their loads features a 200 grain bullet at 1,300fps which develops 750fpe. (This is chrono'd out of a Glock 20 with a 4.6" barrel as opposed to .45ACP loads which are chrono'd out of 5" barrels) A hot .45ACP driving a 200 grain bullet, even at a +P pressure level of 23,000psi will only make 1,100fps and that's out of a 5" tube.
I have extensive experience with both the .45ACP and 10mm and I will tell you that the 10mm is more lethal and maintains lethality at a greater range than the .45ACP. For wild pig, the consensus of hunters (including myself) is that the 10mm is the minimum handgun to reliably anchor what can be dangerous beasts at handgun ranges. There is a reason why no one uses the .45ACP to hunt pig even though many more hunters own .45's than 10mm's. The 10mm also offers better barrier penetration.
Below is a picture of my Glock 20 SF with Lone Wolf 5" Tactical Match barrel. (A stock barrel is 4.6" so the 5" tube sticks out a bit.) With 15 rounds in the clip, it is my go to handgun in case of zombies.
Here's an interesting demonstration of a 10mm with 180 grain bullet at 1,350fps:
