The 17L is the only blue label Glock I've purchased that had a lighter trigger than the other models out of the box. My 17L is 4.5 pounds, all of the others are 5.5.While I'm not a Glock guy, I think the G34/G35 are a couple of guns in the Blue Label program that have different triggers than their non-Blue Label brethren.
Whatever the trigger weight equivalents are, I believe the standard G34/G35 have lighter weight "competition" type triggers, while the Blue Label G34/G35 guns have heavier "duty" type triggers.
Some departments/agencies may want heavier triggers in their guns, but 5.5 is standard.
