...and the manufacturer told you...what?
First place to go with nearly any question such as this is the manufacturer.
In the case of 1911-type pistols, IIRC the 2011 is a wide-body 1911-type, "adjustment" of the trigger involves modification of the hammer and sear. This is best done by someone with the tools and knowledge, e.g., a pistolsmith, as done wrong the result is dangerous.
'Bout the only "adjustment" on pistols such as this is trigger overtravel, where an overtravel stop screw has been fitted.
