• Always think of the pistol as being loaded and
with the safety off until you have established
the opposite through the unloading procedure.
• Allows keep the muzzle of the pistol in a safe
direction with all handling. A safe direction is
towards an area where there are no people,
other life forms or property that is not a

walls, concrete, stone or flat surfaces (water
included). A bullet can penetrate such surfaces
or be ricocheted in an unsafe direction.
• Never aim at yourself or other life forms.
• Never rely on safety mechanisms alone.
Safety mechanisms are not a substitute for
careful, correct and secure handling of the
pistol.
• Always treat your pistol as if the safety
mechanisms were not functioning. The best
safety precaution is a correct, well-trained and
safe handling of the pistol.
• Never shoot with a pistol which has been

Transport Safety mechanisms
4 Transporting the pistol
WARNING!
Uncontrolled discharge of shot
May lead to death or severe injuries
• For your own safety and the safety of others,
always transport the pistol unloaded (see
section 6.7 and 6.8), decocked and closed.
• Never carry a pistol with the hammer cocked
and a round in the chamber.
• Always carry the pistol so that if you fall or
slip, you always maintain control of the
muzzle.
• Transport the pistol separate from the
ammunition, in a locked case.
• Keep the firearm out of the reach of children,
and other inexperienced or unauthorized
persons.
• Follow all applicable Federal, State, & local
regulations regarding the transport of
firearms.
5 Safety mechanisms
WARNING!
Uncontrolled shot discharge
Possibly death or serious injuries
• Never completely trust any safety
mechanism. Any safety mechanism can
break down or malfunction. The safest pistol
is one that is fully unloaded.
5.1 Manual safety Engaging manual safety:
1. Push the safety lever (manual safety) 46 down
fully to engage (see Fig. 6 on page 13). This
prevents firing of the pistol.
Disengaging manual safety:
1. Push safety lever (manual safety) 46 up fully to
disengage (see Fig. 6 on page 13). Red dot is
visible. This allows the pistol to be fired.
5.2 Integral safety lock (key operated)
Locking: (see Fig. 5, on page 8)
WARNING!
Uncontrolled shot discharge
Possibly death or serious injuries
• Pistol must be decocked.
1. Insert key into opening at bottom rear of the
grip.
2. Push key to depress lock and rotate 90
degrees.
3. Remove key leaving end of lock below the grip
surface (see Fig. 5, on page 8, right).
This locking feature prevents the firing of th e
pistol.
Unlocking: (see Fig. 4, left/right)
WARNING!
Uncontrolled shot discharge
Possibly death or serious injuries
• Pistol must be decocked.
1. Insert key into opening at bottom rear of grip.
Push key to depress lock and rotate 90
degrees.

5.2.1 Magazine safety
Removing the magazine fully from the pistol
prevents the pistol from being fired. The magazine
must be fully inserted into the magazine well in
order to fire the pistol.
6 Handling the pistol
6.1 General
The pistol is generally delivered preserved with a
thin, protective grease and oil coating and must be
stripped before being used for the first time,
protective oil or grease removed and lubricated
again. “First use“ (see section 9).
Procedure:
1. Strip pistol (see section 9.1).
2. Clean and relubricate pistol (see section 9.2).
3. Assemble pistol (see section 9.3).
6.2 Ammunition
WARNING!
Inadmissible ammunition
Possibly death or serious injuries and
damage to the pistol
• For your pistol, use only commercial grade
ammunition in its original packing for which
corresponds with the calibre of the pistol. The
correct calibre is imprinted on the pistol .22
Long Rifle.
• Never use reloaded, “refurbished”, hand-
loaded, non-standard ammunition or
ammunition of a different calibre.
• Never use dirty, wet, corroded, bent,
damaged or oiled ammunition.
• Never leave the ammunition lying
unattended.
8US06.01
Page 10
Handling
Information:
The .22 LR ammunition spectrum ranges from
very light loads for single loader guns to sport
load, utility load and on through to high speed
rounds. Unfortunately, however, it is not possible
to adjust a semi-automatic gun to all loads.
We have therefore decided to make an adjustment
to the loads that have priority for use with the
MOSQUITO, which are the two major groups,
utility and high-speed rounds. So to increase the
round compatibility, we provide two slide springs
for every pistol. The bigger bored version is
designed for high-speed loads and is fitted in the
pistol with delivery. The simple coiled smaller
spring (marked white) is for standard loads and is
supplied with the pistol.
Tip:
It has been proven that many types of utility
rounds function more smoothly if the rounds are
lightly oiled.
WARNING!
Uncontrolled shot discharge
Possibly death or serious injuries
• Never oil high-speed rounds, as the
pistol can unbolt too quickly while
shooting.
6.3 Loading the magazine Procedure:
1. Place round on feeder close to the magazine
lips.
2. Push the side lock on the magazine down.
3. Only load the number of rounds that are to be
shot (max.10 rounds).
The number of inserted rounds can be determined
through the slot on the magazine.

Handling
6.4 Loading the pistol (ready for firing) Procedure:
WARNING!
Lacking in awareness of potential dangers
Possibly death or serious injuries
• Never load or unload the pistol inside a
vehicle, inside a building or any other
enclosed space (except in a designated firing
range).
• Before loading always wipe off any excess
grease and oil and check to see if there are
any foreign objects/ material in the barrel.
• Always keep the muzzle of the pistol pointed
in a safe direction.
• Do not put your finger on the trigger. Keep
your finger outside the trigger guard.
• Only insert the loaded magazine immediately
before firing.
• Never cock the hammer back by hand, in
order to prevent the unintentional discharge
of the pistol.
• Never rely on the safety mechanisms alone.
Safety mechanisms are not a substitute for
careful and proper handling of the pistol.
• Never let a loaded pistol out of your hand.
1. Point pistol in a safe direction.
2. Insert full magazine and ensure that it is fully
engaged.
3. Pull slide back fully and release.
– The pistol is loaded and ready for firing in
the single action (cocked) mode.
– The pistol can now be decocked using the
decocking lever. It is then loaded, decocked
and ready for firing in the double action
(decocked) mode.
– The pistol is decocked and ready for firing.

6.5 Firing
WARNING!
Lacking in awareness of potential dangers
Possibly death or serious injuries
• Ensure that the target and surroundings allow
shots to be fired without danger.
• Be certain when firing that your fingers,
hands or other parts of the body are not in
front of, above or beside the barrel muzzle or
the ejector port.
• Never allow a person to stand next to you
where they could be hit by ejected cartridge
cases.
• When shooting, always wear ear protection
and protective eye glasses. Inform other
people close to you about the need to wear
ear protection.
• Stop shooting immediately and unload the
pistol if you suspect that a round is not
inserted correctly, a case is jammed, a round
may have blocked the barrel or a shot sounds
or gives the sensation that it may be “weak”
or unusual.
• Never try to dislodge a blockage by firing
another round.
WARNING!
Missing Dry Fire Plug
Dry firing can cause damage to your pistol
and create an unsafe condition
• Only dry fire your pistol with the Dry Fire Plug
installed in the chamber and the manual
safety off. Observe safe handling procedures
when dry firing – keep the muzzle pointed in a
safe direction!
Procedure:
1. Aim pistol at a safe target.
2. Place finger on trigger and squeeze the trigger
(activates firing).
3. Keep the pistol aimed at the target and fire
further shots as required.
4. Remove magazine and unload pistol. If the
magazine has been shot empty, the slide
remains in the open position. Reload pistol if
further shots are to be fired.
WARNING!
Pistol is ready to fire
Possibly death or serious injuries
• Double action/single action pistols are in a
cocked and ready to fire status after each
firing.
• If you want to interrupt shooting, you must
action the decocking lever to lower the
hammer. The pistol is then in the loaded,
decocked and ready to fire status.
• Once you decide to stop shooting
immediately unload the pistol.
