An abutment adjusting device for a nail gun has a horizontal sliding rail disposed on a bottom side of a nail cartridge of the nail gun. The sliding rail has multiple positioning grooves. An abutment having a containing groove opening upward is disposed on the sliding rail. The containing groove has two groove sidewalls, each of which has at least a vertical guiding channel for slidably disposing a sliding block in the containing groove. The sliding block has a top having at least a protruding part corresponding to the positioning grooves. A first elastic unit is disposed in the containing groove for driving the sliding block to move upward and further drive the protruding part to be engaged into the positioning grooves so as to position the abutment. Thereby, a user can press the sliding block to drive the protruding part to be disengaged from the positioning groove and to release the positioning groove, move the abutment to an appropriate position and release the sliding block to drive the protruding part to be engaged with the positioning groove and to position the abutment for another time.
