I like it just fine in .45Colt in bullets over 260 grains. So does John Linebaugh.
As far as "dirty" one of my favorite colors is the ash of HS-6 on my SS Redhawk. It cleans up real easy and I can easily fire 200 rounds without the revolver binding up.
If it doesn't work good for you in 9mm I am sure you can unload it easily.
