OP, if you are still having issues with your POF, contact Martin Millican (Service Manager) of FEDARMís. Martin helped me out and with the issue on my SMGPK pistol which was having slam fire issues (firing burst). FEDARMís end up sending me a replacement SMGPK. I picked up the replacement SMGPK pistol last week from my local FFL. All is GTG with the replacement SMGPK pistol.
If you want to read the history of my issue, I post it here: https://www.hkpro.com/forum/hk-clone...ml#post3575358
