There is a trigger adjusting screw on the bottom and ahead of the trigger guard.
Later in life after I took mine apart and started the polishing chore, I got to thinking
about this horribly stiff trigger. I called Browning and they in fact told me if I could
not get the trigger down to the lowest/lightest setting in the owner's manual that it
would be considered a warranty issue......

If my memory serves me correct, 3.5 pounds?
I couldn't get below 4.25 pounds.
Some I have held afterwards seem much more user friendly.
Hit and miss I suppose.
I don't argue the accuracy of these T-Bones.
In fact, if I could get this trigger into the ounces, I would lay it
side by side with my two CZ's for pretty targets.
