To paraphrase the most interesting man in the world... "I don't always carry a 45, but when I do, I carry Hornady TAP 230's."
I think it is one of the best self defense load for the 45's (along with Ranger-T 230 +p). I like the extra oomph that the +p gives, but it's not excessive at all in a large frame gun. I have done no testing at all with the round for penetration or expansion. I just know it feeds well in all of my 45s and is accurate (including the 200 gr version).
