A 9x25 converted G40 with 2000+ FPS loads? hmmm...
A 9X25 Barrel in the G40 is the easy button, and the Underwood 90 grain solids probably will be closer to 2100 fps from the extra barrel length of the G40.
I keep resisting the urge to pick up a RIA double stack 9mm and ream it to 9X23. It would trail just behind the 9X25 in velocity, may 100-150 fps with that 90 grain bullet. But it would hold 18+1 and jump up to 23-24 in an extended base plate mag.
