Retired LEO, Range Master and Armorer. Got to attend a lot of good training over the years. From all that including shooting into and out of vehicles, I carry 124+P HST in all my 9mm carry guns. Will take 124+P Gold Dot without issue. I try to buy cases at a time so I tend to not have one load for the Shield and one for the rest. I liked what I saw with the 147 load but had a bad experience with 147 back in the 90's that just haunts me. Its mental on my part but confidence wins. YMMV.
