Anyone had an issue with HST in a Ruger LC9?

[AlphaMike11]

I have a Ruger LC9s.
Love the gun, it has fired over 1000 rounds of 115 PMC bronze and 124 gr PPU (which is kind of hot) and others without a hiccup...
However when I try to use some expensive HST (both 124gr and 147 gr) I have an issue of the slide locking open every 3-5 rounds. no bullet jammed into the ramp; just the slide locking back.
I'm not hitting the slide release or limp wristing.

The guy at the gun shop said small pistols do not like HST and to try other types of self defense ammo. Since that can get expensive quick, I thought it would be a good idea to ask about it here...

Any input?
Anyone else have this experience?

I’d try a round with a different bullet profile. Possibly, the bullet is tripping the slide catch as it’s feeding.

Mine works fine with 124 gr HST +p , shot 50 rounds thru it to see how they did before I carry!
