RE: JAMMING!!!!
Most new guns today benifit from a little wear in period. Plus you may have been short stroking it a bit. Clean the gun and work the action ( gun empty ) a few thousand times and it will get smoother. And keep shooting the clays. You won' t be completely natural with the gun until you shoot it several hundred times. And don' t get frustrated and cop a bad atitude about the gun, this will only hinder the process of getting comfortable with the gun. Trust me, with patients you will get there. The 870 is a fine gun. And with practice shooting it well, will become as easy as scratching your nose.
