Stumbled across this on Lucky Gunner. It's definitely an interesting test they performed. Well worth a look.

I wish they would have tested the Underwood/Lehigh Extreme Defender and Extreme Penetrator line of ammo though. I'm seriously considering switching to those loads in my LCP with the +p extreme defender and the +p extreme penetrator staggered in my magazines.
