Owned a 11-87 12 guage for 4 years now and a 20 guage for 3 years. When I first got each gun the first box of shell fired through them I had problems with ejecting shells. I took each apart and realy cleaned all the factory grease and oil of them and re lubricated them with very light oil and they have been great since. I shoot 2500 rounds through each in a year, Iuse them on everything from starlings , pigeon and doves to ducks and geese , The 20 is the sweetist shooting gun I have ever owned.
