GENERAL TECHNICAL INSTRUCTIONS
DOUBLE & SINGLE SET TRIGGER ADJUSTMENT - SAFETY
Your gun can be provided with set trigger as:
• double triggers: the rear trigger is the set trigger while the front one is the firing trigger.
• single set trigger (also called French set trigger): move the trigger forwards in order to set the
trigger pull, just a light touch on the trigger will then be needed to fire.
Under certain circumstances, an activated set trigger may release the cocked hammer due to the
shock of the mechanism.
Properly adjusted, set triggers will not release the cooked hammer unexpectedly and the
instructions below should be read carefully und trigger adjustments made correctly.

EFORE MAKING ANY ADJUSTMENTS MAKE CERTAIN THE GUN IS UNLOADED.
See figures at page
5 of this booklet.
DOUBLE SET TRIGGER
The rear adjusting screw (# 1) controls the tension on the main spring (# 2) by raising or lowering
the main spring. Turn the screw (# 1) inwards until the hammer will stay cocked without having the
rear trigger “set” (clicked).
If the screw (# 1) has been set inwards too far, the hammer will not fall when the front trigger is
pulled strongly.
If the screw (# 1) is not set inwards enough, the hammer will fail to remain at full cock position
unless the rear trigger is “set” (clicked) first. Therefore, if the hammer will not remain in full cock,
the screw must be turned inwards further until the hammer will remain in full cock without first
“setting” the rear trigger.
NOTE: when making adjustments on screw (# 1) always move the screw in ¼ to ½ turn increments
and recheck your results before making more adjustments.
The front trigger will release the hammer even if the rear trigger has not been “set”. With the rear
trigger
NOT set, the pressure required to release the hammer will be much more that when the rear
trigger has been “set” (clicked).
The front trigger adjustment screw (# 3) changes the amount of movement or travel, which the
front trigger, will have before the hammer is released.
Turning the adjustment screw (# 3) inwards will reduce the front trigger movement required to
release the hammer. Turning the screw outwards will increase the required front trigger movement.
If this screw (# 3) is turned inwards too far, it will not “hold” the setting against the rear trigger sear
notch (# 4).
Proper adjustment should produce a very small trigger movement with light pressure required.
Such a setting helps a good shooter to obtain better accuracy.
We recommend to periodically verifying the screws that may loosen due to the shot vibrations.
For some set triggers there is a side screw (# 5) to make sure that the screw (# 1) doesn’t loosen.
This however does not happen too often and only to guns that have very strong recoil.
SINGLE SET TRIGGER
A small adjustment screw (# 1) is located right behind the trigger blade (# 2). Turning this screw
inward will reduce the pressure required to release the trigger and turning the screw downward will
increase the required trigger release pressure.
Pressing the trigger blade forward does the actual setting of the trigger.
The screw (# 1) has a slot head to allow a small screwdriver to be used and there is also a small-
drilled hole, which allows a pin or small nail to be used to turn the screw.
Note that gun equipped with the single set trigger can also be fired without first setting the trigger.
With a cocked hammer simply pull back on the trigger and the hammer will be released. Of course
the amount of pressure required will be greater than when the trigger has been “set”.
WARNING
If the set trigger has been adjusted for a short and light release, it may be possible that a strong
shock or a strong vibration may cause an unexpected hammer fall.
