My SD ammo of choice is Ranger 'T', but they're getting hard to find, and expensive. My go-to these days is HST, but you can't go wrong with Gold Dots, either. I prefer heavy-for-caliber bullets, mostly 147 gr., but will grab up 124's when a good deal presents. I avoid 115 gr. loads, except for casual plinking.
Hey, just a concern, when picking 9mm self-defense ammo, make sure it actually feeds reliably in your EDC gun. Even the best rounds can cause jams in some pistols, so testing is importnt
