I wouldn't be surprised if this gets moved to one of the handgun forums. Lots of discussions there about 9mm ammo.
WWB 115 grain is good for practice. It is FMJ, right? For myself, I prefer 124 grain, but lots of people use 115 grain. Actually I do too, not just in my pistol; I use 124 grain in my pistol, and the cheaper 115 grain stuff for plinking with a Highpoint 995.
Lots of people buy the WallyWorld WWB 115 9mm for practice. But for SD/HD, you'll want some good hollow points, and that will set you back more. I use Hornady TAP in 124 grain for SD/HD. I shoot a few through my PT24/7 now and then, just to make sure it works, but feed it a steady diet of Remington UMC 124 grain FMJ for getting lots of trigger time.
