870.....870.....870. Been using one for 40 years. Never failed me. I am a lefty also. I never even notice if the shells are ejecting across my face. I just got used to it a long time ago. A lot of folks now ask me if I am using an auto as my shots are so close together. I don`t even know I`ve pumped the shotgun as it just comes second nature to me now.
