Blue Dot is my favorite powder for the 9mm. It burns fairly clean, provides excellent accuracy, and you can't double charge a case. It does have a bit more muzzle flash than other powders I've tried and doesn't meter quite as well as ball powders, but its' benefits far out weigh the increased muzzle flash. I have loaded tens of thousands of rounds of 9mmP ammo with Blue Dot, and haven't found anything that works as well for me over the years.... But that's just me, and everyone has thier own preferences........
Anyway, the two loads I use the most are:
115 grain Remington JHP with 7.5 Grains of Blue Dot loaded to an overall length of 1.120" . Velocity runs about 1,150 depending on a number of factors. (I also use 8.0 grains of Blue Dot with the same bullet and oal when I want a bit more velocity. 8.0 grains gives around 1,250 fps.)
124 grain Remington JHP with 7.5 Grains of Blue Dot loaded to an overall length of 1.120". I don't recall the velocity exactly (I'm at work and my reloading data is at home...), but I believe it is about 1,100 fps.
Both of these loads shoot quite well in my guns, and function my lugers 100% . Neither load is a maximum load. Please note that these loads are loaded to a bit longer overall length than many loads that are shown in reloading manuals. I have grown to favor the 124 grain load, but some of my guns shoot better with the 115 grain load. The 124 grain load shoots a bit higher than the 115, so you can change bullet weight to try match your guns sights.
I hope this is useful information.
