Not sure I agree on the 10mm. It significantly outperforms the .45acp and the 9mm when properly loaded. It did fall by the wayside for a while, but there are a lot more models currently offered, and it's easier now to find factory loads on the shelf. The odd thing is that most of those loads I'm seeing locally are still 10mm Lite.
Using Undrrwood Ammo in both the 10mm and 45 ACP in +P shootng both I did not and do not see any superiority in the 10mm over a properly loaded 45ACP
I got banned on another web site for a debate that happened on this site. That's a first
