I have shot about 400 rounds of WWB 115 HP, WWB 115 FMJ, Federal HS, and Corbon +P 115 JHP in my KT P-11 without any problems so far. I have read elsewhere that WWB does not feed well in the P-11, but it has worked in mine. The Corbon seems a little hot for this gun, but feeds fine. The little gun is going to get some carry time soon and I need to choose a good carry round for it. Can someone with KT experience tell me what the best defense round for the P-11 is?
