Hi. Have had at least half a dozen Trackers since they were release, in both .177 and .22, and in walnut and beech (also had a couple of the longer barrel Viscount derrivatives, too), and iirc, they never had a two stage trigger, just a single stage release, so maybe your trigger is working perfectly but the tension screw is wound in too far -- unless an after market 'Chambers' trigger unit has been fitted, in which case, contact Chambers? Hope this helps?
