As on an AR-15 JP rifles recomends moly paste for the sear on the triggers they provide. I have purchased Honda moly paste 60 which is 60% moly a very high content. Comes in a 3 0z. tube for about $10 bucks. Very good stuff. Have put a dab on the sear and striker block on the Xd with fantastic results over using a drop of oil. Stuff is extreamly creamy and tacky.
