Looks like this bad guy had a plethora of holes punched in him with ball ammo (full metal jacket). I'm sure that the right expanding ammo would have taken him down much faster and with a lot fewer rounds. Look at this ammo test using pork ribs and sheet rock plaster where the ammo was 40 S&W from a Kahr PM40 and +P 380 ACP from a little (8.3 ounce) Kel-Tec P3AT:


The Buffalo Bore ammo is amazing even from the little Kel-Tec. If the BG had been shot 33 times with a Glock 19 using Buffalo Bore +P+ Speer Unicore rounds, he would have been "shredded". Anyway, the bullets do make a world of difference.
