You are a bit on the light side. The Alliant Powder 2005 Reloaders Guide lists the following for a 125 gr. FMJ in 9mm:
4.9 gr. Bullseye = 1155 fps = 32000 psi

I loaded some 124gr fmj with 4.1 grs Bullseye. They fired fine and were OK for accuracy but on several occasions my slide did not lock back on a pistol that eats anything. I wondered if 9mm needs a slower burning powder??
I also noticed that the ejected brass was going more forward or hitting me in the head rather than high and to the right. I thought I read somewhere that how the brass ejects can tell you something about the load??
