I like the Federal HST, either 147+P, 147, or 124+P flavors.
I also have carried a lot of Georgia Arms 124+P Gold Dots, some time back before that it was the Federal 9BPLE (I admit, I read two of the Marshall and Sanow books and they did influence me. Now I think they are an interesting read, but not reliable or relevant to contemporary JHP designs).
I've also carried Fiocchi Extrema 124 or 115 XTPs (can't remember which), Fiocchi 147 JHP, WWB 147 JHP, Remington UMC 115 JHP.
I'm sure there have been others too, but those are the great majority of what I have carried. I liked the 147+P HST best of them all.
