I have done extensive ballistic gel testing. Federal HST 124gr or HST 147 gr standard pressure is what you seek. 124gr HST performs much better out of a short barrel like the Shield or Glock 43 than all the others. Corbon DPX 115+P performs well. IN a short barrel the gold dots 124+P did not perform well at all failing to expand 6-7 out of 10 times. They did perform better out of a full size duty weapon
