I carry Hornady Critical Defense. I practice with the cheapest and carry the more expensive. I would not carry rounds that are not meant to be used for SD. Reason is I went to the range one time. Had been carrying some generic HP rounds. I decided to shoot the rounds that were in the gun first. The first round I shot I had unburned gun powder block back in my face. It was a good thing i had my glasses on and not in a SD situation! I believe the reason that this happened is plinking rounds aren't designed to be carried and deal with the sweat and abuse on a daily basis. So I will continue to carry the Hornady Critical Defense rounds.
