I use Hornady critical defense hollow points. They are 115g nickel plated. They feed extremely well in my Glock 19. I haven't tried them yet but Hornady also makes a line called critical duty. They are pretty much the same casing as the critical defense only the actual bullet is larger and the powder is loaded at 135g. But I have never had one problem with any of the ammo that I use. I just trust Hornady the most.
