I don’t know how you can “run” without some serious aggravation from that pistol. I certainly don’t run with a belt and a pair of pants. I use running clothes. I am still trying to figure out how to run with my Ruger LC9S. It’s small but I still feel it no matter where I put it while running.
The holster makes a big difference. The Fobus paddle has worked well for me.
It also helps to cinch up the belt snuggly.
Lots of pistol carry is cut and try and see what works.
