If you got a DW with a light trigger; it's either had a trigger job or (more likely) a spring kit added. I've owned several and all had a relatively heavy trigger pull. A switch to factory springs will up the trigger pull in both cases. If it's had a trigger job; most replace the springs as well as polishing the contact areas. On the small/med frames it's an easy do-it yourself job; on the max and large frames it requires pushing out retaining pins and careful removal of the trigger group.
