I can honestly say my G19 has never had a hiccup with WWB and my JHP carry ammo, but as of this past Saturday I have ONLY shot approximately 600 rounds through it. 500 of those have been the bulk pack WWB FMJ you get at Wally World, and the rest have been testing and burning up of my old carry ammo which I just swapped for new stuff last month.
Before that I had a XD9 and a XD9SC that never had any issues during the time I owned them.
I did have a P22 that had an occasional FTRTB, and FTE.
