Power Pistol will work very well for what you want - meters well, very good velocity and excellent accuracy. Start at 3.4 grains and work your way up to about 4 grains. Use a medium taper crimp and adjust OAL using your barrel so the bullet is just off the rifling.

PP is a very good powder for 9mm. However it is a little smoky and has quite a flash so is not the best for indoor tactical matches.
