Cameras Don't Lie: 9mm vs .45 ACP

The age-old question, 9mm vs .45 ACP. For some, this has been asked and answered already. For others, the debate goes on. In this segment of “Cameras Don’t Lie,” competitive shooters Patrick Sweeney and Jim Tarr head to the range to put the vaunted loads on record, and then consider the footage.  

Using nearly identical guns, both from the Remington family of polymer-frame, striker-fired RP pistols, loaded with Hornady ammunition, our shooters set out to compare often unseen measures such as muzzle rise and slide-lock time. Thanks to the aid of high-speed cameras, they can finally put to the argument to rest. Which round is better, 9mm or .45?
