First stage travel:
Use the setscrew (d) to adjust the distance between the rest position of the
trigger finger piece and the let-off point.
- To reduce the first stage travel, turn the screw clockwise.
- To increase the first stage travel, turn the screw counterclockwise.
To increase the trigger pull weight:
The trigger pull weight is the sum of first stage trigger weight and second stage
trigger weight. It can be adjusted as follows:
To increase the first stage trigger weight:
Increase the first stage trigger weight and the total trigger pull weight by tight-
ening the screw (g). If you want to increase the first stage trigger weight only,
you must then open the screw (c) and check the trigger pull weight.
To increase the second stage trigger weight:
Increase the second stage trigger weight and the total trigger pull weight by
tightening the screw (c). If you want to increase the second stage trigger weight
only, you must then open the screw (g) and check the trigger pull weight.
Let-off point:
Set the let-off point using the setscrew (e).
To move it forward, turn the screw clockwise.
To move it back, turn the screw counterclockwise.
Pawl intersection:
With the pistol cocked (training slide at position “T”) tighten the setscrew (a)
until the trigger is released. Then turn the screw back by ⅛ to ¼ of a turn.
The setscrew (a) is set at the factory and if possible should not be altered.
