CZ ringneck: What is the best plan of action for making the triggers reasonable

[cz75bmb]

I recently acquired a nib cz ringneck, 20ga.  What is the best plan of
action for making the triggers reasonable.  The first barrel is 8.5pounds
and the second one 10.5pounds. 
   I did contact CZ and they said that 7pounds was the lowest they could
go under warranty-repair.
   (It's a side-by-side of course with one trigger.)
   (I would like to get both barrels 5pounds or less.)

I have the same issue with my ringneck 12ga., any recommendations for lightning trigger pull would be appreciated.

bump
it's a single-trigger.

Having read this, I had to check my brand-new Sharp-tail Coach.     4 lbs on the button (and crisp!) for either barrel.

Sorry....

I left it with a gunsmith.  I don't have high hopes though....

came back from the gunsmith with 7.5pound trigger on each barrel.  wanted 5pounds or less.
