Hi recently bought the Rem 1911 R1, right from the get go if you load the mag with the max seven rounds it will not feed just jams below the breach, after clearing the jam you take out a couple of rounds and insert the mag again it fires and feeds just great, and with a full mag of seven straight after that initial five round, tried several different brands of round headed ammo with same result, can anybody help?
