Maybe you need to be more careful as to which weapons you use for self defense. That you own a few pistols that apparently have failure to feed issues with hollow point ammunition may not be due to the ammunition but due to the pistols. I do not own any pistols that regularly have failure to feed problems with decent quality JHP ammo. Most commercially available ammo from well known manufacturers is of high enough quality that it should not cause such problems. If you are using decent quality ammunition and are having failure to feed issues, I would highly recommend you also check your pistols as being the possible source of the problem.
I highly disagree with you. I have dealt with all kinds of firearms since my Army days back in 1968. I also spend a lot of time at local ranges. I see quality firearms fail to cycle due to certain types of factory "defense" ammo.
Well there you go, I think you just made my point at least in part. You have a Glock 19 that feeds everything while other guns apparently do not funtion properly with the same ammo. It's maybe not the ammo then - is it? My Beretta 92 series pistols also have fed almost every round put through them without failure, regardless of ammo, the only other guns that ever came close were my issued Glock 19 and m`y personally owned Glock 26. They were not as good as the Berettas though - they could not reliably feed some old S&W semi jacketed hollow points I had - failed to feed about every third round - but the Berettas fed them like flowing water.
