I have been using Hornady Critical Defense for a long time. Recently I had an experience that led me to believe that particular 115 grain bullet had less than desirable penetration. I have considered 147 grain Gold Dot. But when I went to buy them, I did not see any. I did see Hornady Critical Duty which are a 135 grain +P round. I know that a friend uses them, so I thought I would give them a try. Finally took them out this afternoon. I told my wife to listen from the house to see if she could tell if they were louder. She said they were. 
I had read on a Kahr forum that +P rounds might be a handful out of my CM9. I noticed a slight difference, but not much. Accuracy was good and no trouble with feeding. What do others use, and how many rounds do you usually shoot out of your pistol before you are comfortable carrying that particular round. Self defense rounds are very expensive when you usually spend about $5 for 50 rounds reloading.

I carry these in both my S&W Shield and my Diamondback DB9
