I was wondering as I was shopping around for some more carry ammunition, which ammunition has actually passed the stringent testing set up by the FBI? In addition to that, which ammunition excels being fired from a sub-compact barrel? I thought this was a good read and has helped me in deciding to carry the Speer Gold Dot 147 gr 9mm in my Sig Sauer P239.
Speer Gold Dot Ammunition, Ordnance Gelatin Calibration, Anatomically Correct Targets
But hey, if you happen to know where to find any recent data that will help some of us decide what to carry in our SD guns, please post.
