Before installing, removing, or performing any maintenance
operation, always remove the magazine from the fi rearm, open
the action, and visually ascertain that the chamber is empty and
the weapon unloaded. Failure to do so can result in potential for
serious injury or death to the user and others in the vicinity
ATTACHMENT TO THE WEAPON
Before installing or removing the suppressor, remove the magazine,
open the action, and visually ascertain that the weapon is unloaded.
The BLACKSIDE-40 is supplied with one of two standard threads in
the mount, depending on the weapon:
(1) 14.5x1 mm (LH): HK USP Tactical, .40 caliber
(2) 9/16-24 tpi for other .40 caliber barrels. The majority of .40 caliber
threaded barrels manufactured in the United States use these
threads.
After removing the thread protector (if any) on the weapon, screw
the suppressor fi rmly hand tight. It is not only unnecessary to use tools or
grip enhancers to screw the suppressor on, but use of such devices will
accelerate wear and deformation of the threads. Periodically during use,
check to be certain that the suppressor is not unscrewing.

weapon system are changed. Except in rare occasions, there will be a

pistol, if the POI shift is objectionable, provision is made so that it can be
adjusted so that it lies in the vertical axis (the easiest to accomodate). The
procedure is as follows:
1. be certain that the weapon is correctly sighted in without a suppres-
