Hickock is the man and I thought this was a very intelligent way of displaying recoil. http://www.youtube.com/watch?v=urxT53-Ukig If you look closely using the target as a grid, the 9mm seems to rise just as much as the﻿ 40sw. 9mm starts @ 3:40and The single fire rises to between the 3rd/4th ring, rapid fire 2 ring. the 40sw, @ 4:43 single rises just about the same maybe a hair higher on average into the 3rd/4th ring and rapid fire seems to be in the 2 ring as well. Maybe a hair more push back but I must say to me there doesnt seem to be that much of a difference and the 40sw seemed extremely controllable The sound of the 40 is louder but as far as muzzle rise, there doesnt seem to be a significant difference. I would call the 2 very very close. No we don't know what Hickock felt but you always hear ohh the 40 is snappy, well to me it doesnt look like it in this video, I think there is slight increase in recoil from the 40, but nothing dramatic at all. What do you guys think??
