JBM - Personal - HK USP Trigger Smoothing - 11

Final Reassembly

Check the hammer strut again to make sure it is in the slot on the bottom of the hammer and slide the hammer spring over the strut. Make sure the hammer is down or you will have to compress the hammer spring more. Insert the lanyard loop insert into the bottom of the frame and align the hammer strut and spring. When aligned, insert the lanyard loop insert pin. This complete reassembly of the frame. Ensure that the trigger can be pulled and that everthing works correctly before putting the slide back on.
