You have to manually take out the magazine when switching modes. The gun barrel extends when in SMG form to make room for the mag and the bullets into the feed. The trigger is to activate the transformation when the magazine is not inserted. Think back to Qrow's weapon and how he holds the trigger to activate the transformation. Sort of like that.
