I'm planning on making one of my 17D lowers into a PCC. Having never put a PCC together before, in what little reading I've done thus far I've come across more than one person talking about issues with weaker hammer springs from drop in triggers causing issues in the PCC. More and more, I'm reading about people taking mil-spec triggers and possible only updating the trigger spring, while keeping the original hammer spring. Does anyone here have any experience with aftermarket triggers in their PCC's (going with Glock build with the ramped bolt). Any info or insight would be appreciated.
