Any modern ammo from a reputable company is going to serve you well, just make sure your gun likes it. Seeing that you're shooting a G21 I don't see you having a problem with that. Some of the local police departments around here issue the HST and it seems to do fine for them. However, just my preference, but I like the Winchester PDX1. At work I carry the 124 +p in my G17. I use the 230 grain PDX1 in my Sig 220 and XD45. Just find one you're confident with and that your gun shoots well. If I didn't shoot the Winchesters it would be Hornady TAP for me. I've seen them work first hand and have total confidence in them.
