The Andrew Sperr NY SP trooper killing in 2006 was what prompted the NY SP to move from 9mm to .45 GAP. I've been trying to find more detailed info on what the wounds were to the two murderers. This is the most I've found so far: http://www.theppsc.org/forums/showthread.php?t=732 Despite being shot, Bennett says Sperr fired off several rounds at Horton and Adams. Horton received four gunshot wounds. Adams received one gunshot wound to the back. Anyone have more details? Wanna kill these ads? We can help!
