Anyone got tips on howto / what to polish in a 590A1 to make it smoother ?
As many parts are stampings, I would work to gently file off any sharp/rough edges that may exist. Of course don't touch the extractor claws and sear, etc. Clean up the action bars and maybe inside of slide tube... Look for places that have been "rubbed" inside the receiver and see if they will clean up on the piece doing the rubbing.
Lots and lots of shots down range. It will smooth itself out.
Buy a set of MCarbo trigger springs for $20. Takes about 20 mins to install.
