I am ready to install the light trigger return spring onto my p30. I purchased it from HKParts. I can not find any instruction videos. Do I have to disassemble the entire grip module or just the pin that holds the trigger?
Any assistance is appreciated.

Have you checked the HKRro forum Reference Library? You may find some helpful posts and photos there. I hope you also bought the special spring pliers because the trigger spring replacment can be a bitch.

Thank you Gary, I did buy the pliers and will check HKpro’s site.
P.S. I went to SLU, undergrad and Law. It has been my second home since.
