I shot thousands of 155 grain traditional lead bullets thru my M&P40 1.0 using Ramshot Silhouette and had zero issues with leading, and was surprisingly clean.
Fast forward about 10 years and a friend bought a 9mm Shield. He was having leading issues with 124 grain bullets. I told him to try Ramshot Silhouette and he said that his problems went away.
I'm currently running a 135 grain TC Blue bullet with a light load of Clay Dot and will have to check the accuracy in the 9C 2.0. 124 HP Precision Delta shoot pretty well from what I remember but the last time I shot it was pre 'rona.
