I'd stick with the Federal HST since you already carry it. My agency carries .357 Sig (for now) and we are using the HST ammo. Lots of rounds with no hiccups. We also had good results with Speer Gold Dot. The only round I'd stay away from is Remington Golden Saber. Although not a cronic problem, we had our fair share of hard primers which failed to detonate. In fact, we made it a habit of keeping a magazine of Gold Dots to save for the street in-between range qualifications.
