Generally speaking any 115 grain will do. I think the 9mm was designed with this weight for optimum performance, but you could also try other weights as well as other manufacturers as well, actually what I am concerned with is is it clean ammunition (doesn't leave reside all over your hands) and does it feed into the chamber well to not cause any feed problems, so far I have found none that do so, but I make sure the feed ramps are clean and shiny on all my pistols!
