Thinking about getting left-hand 870 for HD, but all they seem to have is the 26" - 28" Express model and barrels. Is a 18.5" barrel not available for the left hand action 870 or am I just not looking in the right place? I used to have an 870 Express that I knew I could shoot 2-3/4" and 3" shells. I saw one the other day that just said "Remington 870", not Express or Express Magnum. It had the laminated stock, 3" shells OK in that? Thanks in advance.
