This question was originally asked in the AXIS section, hence all the confusion.
The red blade accutrigger denotes the 6 oz. version that came on model 12 target actions. The red blade is only an indicator, itself has nothing to do with the light trigger pull. The lighter trigger pull comes from the sear, which has a different engagement angle and is identified by the dimple under the thumb piece. The red blade accutrigger will fit on the Axis, however the mating sear from the model 12 will not. The Axis sear is totally different.
