On the contrary, Haz.....I think the Ft. Hood attack shows how effective the 5.7 is in a close-range situation...esp. when the shooter was engaging other shooters shooting at him. I doubt any pistol short of a Magnum-class caliber could have done any better....
I wonder if one of the unintended consequences of this event will be that more gunmakers will make 5.7 pistols.....say, a Glock 41 or Springfield XDm in 5.7?.....
