I don't obsess over duty-grade ammo that has been heavily vetted by the manufacturers and correlated to street results under a wide variety of circumstances. Federal, Speer and Winchester all make loads that fall into that category. As long as it functions in your gun, I don't think it really matters. HST 147 should be fine. Personally, I carry standard pressure 124 Gold Dots, but that is only because I have shot a bunch of it over the years in a bunch of different guns, and I have an decent supply on hand.
I do keep some magazines loaded with penetrator ammo, including Mackay's +P hard cast and Lehigh Xtreme Penetrators, on hand for off-pavement carry or unusual circumstances.
