Shooting it about 1500-2000 times will take care of most any polishing needed.

I agree with the first answer. Shoot it and it will improve. My Sig P220 is silky after years of use (even with a heavy DA pull). I'm working on getting my XD-40 up to 1000 rounds (by me) by year's end.

You can add some tiny amounts of grease to the trigger bar/striker safety lever/sear contact points, as well as on the trigger bar and sear springs where they contact metal, and that will help a little bit. But you are still trying to overcome a pretty stout sear spring so there's only so much you can do before you have to start thinking about a trigger job and lighter sear and trigger bar springs.

If you want to locate the correct polish points, you have to shoot your gun enough to wear down the trigger a bit, then when you dissassemble, you can see where the contact points were and polish/deburr accordingly.
