The ones they keep refering to jamming in the comments page are a different design which I personally have not used in a semiauto.

https://www.lehighdefense.com/9mm-luger-p-90gr-xtreme-defense-ammunition#:~:text=The%20Xtreme%20Defense%20(XD)%20Technology,an%20individual's%20personal%20comfort%20level.

The max expansion rounds feed just as well as any other hollow points I have run through both 9mm and 45.  

I have also ran some of the lehigh match solids and the controled fracturing through different semi auto rifles with out any issues.  The xtreme defense, cavitator and xtreme pemetrators I have not played with yet, depending on the gun and feed ramps those designs looks like a jam waiting to happen which is part of the reason I have not tested those.

Speer gold dots have also been a go to for defense in .45, have not used in 9mm personally - the .45 gold dot had good penetration and expansion in water jugs. and feed just like any other hollowpoint.
