Yes you are correct! The 10mm is very close to the .41 mag and it is the most powerful round you can get in the Glock.
One of the hottest 10mm loads I have seen is from Buffalo Bore. 180gr Speer JHP 1,350fps 728 ft.lbs
The recoil from this load would get your attention
I know you can get some pretty hot Corbon and Buffalo Bore .45 & .400 Corbon ammunition but the 10mm would still be on top.
