GUN HANDLE
DISASSEMBLY
The internal parts of the gun handle may be
inspected or serviced if necessary.
The gun handle consists of two halves that
are held together with a collar on each end.
To open up the handle, turn the collars
approximately 60 degrees counterclockwise
(the same direction as removing a right
hand thread) until the collar reaches a stop.
Then pull the collar off the gun handle. If the
collars are difficult to turn, position the gun
handle against a corner, place a screwdriv-
er against the tab on the collar and give the
screwdriver a sharp blow to turn the collar
past an internal locking rib.
