Most heavier 9mm P cartridges are loaded to much lower velocities.
Usually, in the US, for subsonic speed for use with a supressor.
Just for the record 124 gr x 1000 fps = 124K, a 140 gr bullet at 885 fps has the same "impulse".
I have fired subsonic 9mm rounds, 147gr - they will not operate the toggle to its full rearward position!
