Norma JHPs worked just fine. My first load in .40, in fact. Just threw a middle-of-the range powder charge in (sorry, don't remember even WHAT powder) and shot bowling pins with the gun. No problems knocking them over, and accuracy testing was no better and no worse than other JHPs
Later experience leads me to recommend against WW231, at least if you're in a hot climate. I'd suggest these days Power Pistol if you don't mind flash, and Unique or Herco for a much milder, more vision-friendly orange flash. Ramshot Silhouette may be the best if it's really the same as WW-WAP--in other bullet weights, WAP was very low-flash.
