The 9mm Super Comp (9x23) is of a new design with a new head stamp as of July 7, 2003. We have changed the head stamp to read 9x23 Comp to allow easier identification because it looked too similar to the .38 Super Comp head stamp. At the same time, we slightly changed the interior design to allow the seating of heavier bullets (i.e. 147 grains) but change will in no way affect performance of case for use with lighter bullets.
