I recently had the same problem with my 6.5. Sometimes I had to pull so hard that my finger almost hurt from pulling the trigger.
After Disassembly of the frame and removal of the trigger, I found the sides of the trigger, inside the frame to be "slightly gummed up" with old paint residue. A little solvent and a toothbrush helped to some extent, then a light wet-sanding with 1500 grit sand paper made it good as new. Smooth Trigger Pull and auto triggers like a dream.
I gleaned the info above from watching some of the videos mentioned above by CCMachinist. TF does a Fine Job of explaining almost anything about a CCM Marker.
Now I am just waiting for CCM to get my new Aluminum Trigger to Anno, to be made into a beautiful Dust Red.
