outside of the trigger guard.
• push down on the control lever (decocking

On Variant 9 and 10 pistols, to lower the hammer
on an empty chamber, the following steps must
be followed with extreme care. remember: lower-

requires pulling the trigger. The action of pulling
the trigger bypasses the passive safeties which
are built into the USP. If there is a round in the
chamber when the hammer is being lowered
manually, and if the hammer slips, the gun could
discharge causing possible subsequent property
damage, injury or loss of life....

fault of the manufacturing process), the primer
