10mm recoil is exaggerated on the errornets. Its much like the so called stopping power of the 45acp. Does a 10mm recoil more than a 9mm? Yes. However, a medium frame 357 Mag is MUCH worse. MUCH MUCH worse. Does the 45Acp have the ability to stop an assailant? Yes. Will it "blow him clean off his feet" (as I've read repeatedly). Absolutely not. Shot placement, bullet selection, clothing penetrated, etc all contribute to the success or failure of the round's performance.
