I'm not sure there is a distinct 14 inch Express barrel. Largely because there's no real market for them in the US, PD's are the largest consumer, and may run both "P" and "Express" guns due to cost. I have 2 barrels sitting in boxes that are marked 870 XBL - 12/14 Cyl - PL EXP. Both are matte blue with pedestal beads and mag cap detents. I'd assume from that "PL EXP" that the barrels are the same for Police and Express guns. The part number on mine is 80056. Gravel Defence Division lists the part as "LE Only".
