Just last week I tested out some BE loads in 9mm. I also was using 124gr plated bullets and a G19, so you're in luck. Off the recommendation of someone on this forum, I forget who, I used 4.2gr.
They shot great. Very low recoil and very accurate. BE is dirty and the cases came out scorched, but it shot very nicely. I just loaded up some more the other night I liked it so much.
I loaded to an OAL of 1.142" because that's what my dies are set to. I load all my 9mm to that OAL.
Hope this helps.
