Apparently they do offer a version that does not use compensators.
But also pay particular attention to the velocities
of the 180 and 200gr 45 super bullets... The identical same
velocities as full power 10mm ammo for the same weight bullet.
The 45 super could be offering same performance ( weight of
bullet and velocity ) as the 10mm with considerably less
headaches in terms of component and ammo availability
as long as you are handloading. Note that the 45 super
requires the extra strong and thick cases sold by Starline.
