I assembled a new LPK from PSA, and the disco will not release unless i manually push it down with a punch then the trigger will catch the hammer. I have checked twice making sure the disco spring is oriented the correct way and seated completely. I know i can time the disco if it ISN'T catching the hammer by sanding the front, but can i do the opposite for the back if it is catching the hammer and not releasing? Any advice would be much appreciated,

You shouldn't have to sand anything nor would I recommend it.  I would completely take out all of the guts, ensure the trigger spring and hammer spring are installed correctly, reassemble, function check and take it from there.  I would suppose there is an off chance your lower may be out of spec but that isn't something in my experience you run into very often.

What would be out of spec? trigger pin holes in the wrong place im guessing?

Burr on the hammer or disco hook. Clean it off carefully with a die-maker's file or small whet stone until the trigger releases the hammer properly.

And if it ever came to it, the answer would not be "sanding/filing the back", but instead shimming the disconnector foot at the front.

So carefully file the disco hook or the mating surface on the hammer? or both?

Thanks, thats why i asked, not in the mood for making things dangerous. How would one go about shimming the foot?

There was a slight burr from the cast on the disco, cleaned that up and she now disconnects when the trigger isn't held as it should. Thanks everybody for the help and advice! Much Appreciated.
