I can shoot a 147 gr. Gold Dot out of the 2" barrel of my Model 940 at 1080 FPS using Power Pistol. Cases do not stick in the chambers and any increase in powder charge gives no gain in velocity, which leads me to believe that I have reached the ideal combination of bullet and powder charge which can burn in my 2" barrel.

Keep in mind that the 940 is a revolver with offset cylinder stop notches and I do not have to worry about things like unsupported chambers. My load might not be safe in your 5906. But it is a good indication of just what can be done with Power Pistol in the 9mm.
