Went to the range today with a friend and took these. Kimber Pro Carry II, Springfield XD40SC, Ruger SP101, and CZ75b 9mm Here's the range where we shot. We brought some wet newspaper and here's the results of that. How about that Winchester Ranger 230gr +P??? It was an impressive sight. The 9mm GDHP's worked great too. I think these will be my go to defensive rounds in the future based on the results. I really wasn't impressed with the Critical Defense or Hydrashok's either one. I'm sure they will do the job, but those others look nasty!
