Only slightly "wrong."Wrong.
10mm in full-power is .357 level.
.41 Mag smokes 10mm unless you wimp out and compare the hottest 10mm loads to lightweight .41 loads.
Apples to apples comparison: similar bullet weights & type, by the same manufacturer.

Concentrating on the 4" barrel length, more common with CC pistols, with more common bullet weights, the 10mm still ranks above the .357 and is comparable to the 41 Mag! Additionally, it is as controllable as the .357 and more so than the .41 Mag.
