THE TRIGGER PULL MUST NEVER BE SET TO LESS THAN 3 LBS
HOW TO
“SET”
SINGLE SET TRIGGER
The FRONT trigger is the firing trigger, it can fire both as a normal trigger or as a “double set trigger”; the
REAR trigger is the “set” trigger. You ‘set’ the trigger by pulling the rear trigger until it clicks. At this point you
can
release the fully cocked hammer by applying a light pressure to the ‘firing’ (front) trigger.
WARNING: A N IMPROPERLY ADJUSTED SET TRIGGER MAY RELEASE THE FULLY COCKED
HAMMER DUE TO A STRONG IMPACT TO THE MECHANISM . P ROPERLY ADJUSTED SET TRIGGERS
WILL NOT RELEASE THE COCKED HAMMER WITHOUT PULLING THE FIRING TRIGGER . R EAD
CAREFULLY THE INSTRUCTIONS BELOW ON HOW TO PROPERLY MAKE TRIGGER ADJUSTMENTS .
WARNING: M AKE CERTAIN THE GUN IS UNLOADED B EFORE MAKING ANY ADJUSTMENTS .
REAR TRIGGER ADJUSTMENT
Point your firearm in a safe direction, make sure it is unloaded and put the hammer in the half cock position.
1. Screw #1 controls the tension on the main spring (#2). See picture 1.
2. Turn screw #1 in a clockwise direction until the hammer stays cocked when it is pulled to fully cocked
position.
NOTE. If screw #1 is set inwards (clockwise) too far, the hammer will not fall when the front trigger is
pulled.
If screw #1 is not set inwards (clockwise) enough, the hammer will not remain at full cock position unless
the rear trigger is “set” (clicked) first.
3. When making adjustments on screw #1 always move the screw in ¼ to ½ turn increments and recheck
your results before making more adjustments.
WARNING: THE FRONT TRIGGER WILL RELEASE THE HAMMER EVEN IF THE REAR TRIGGER HAS
NOT BEEN
“
SET
”.
FRONT TRIGGER ADJUSTMENT.
1. The front trigger will release the hammer even if the rea r trigger is not “set” (clicked).
2. The front trigger adjustment screw #3 (see picture 1 ) changes the amount of movement, or “travel”, the
front trigger needs before releasing the hammer.
3. Turn screw #3 in a clockwise (inward) direction to reduce the front trigger movement required to release
the hammer.
4. Turn screw #3 in a counterclockwise (outwards) direction to increase the required front trigger movement
required to release the hammer.
NOTE. If screw #3 is turned inwards too far, it will not “hold” the setting against the rear trigger sear notch
#4.
