I often hear about the Pedersolis (12 gauge) that are 5 pounds something. Which years, models are these? I have a 12 and a 20. Both are over 6 pounds with the 12 being 3 ounces heavier than the 20. I would love a 6 pound or less ML SxS. The weight adds up after my typical 2-6 miles a day birdhunts.
