Two gauges, one gun. The 686 Silver Pigeon I Combo includes matched 28" barrel sets in both 20 gauge and 28 gauge, each built from Beretta's cold hammer forged Steelium tubes with a vent rib and blued finish. Swap the barrels and the same fitted stock, receiver, and trigger serve two very different jobs the 20 for waterfowl days and heavier target loads, the 28 for upland birds and the sweetest swinging skeet rounds you will ever fire.The receiver is the Silver Pigeon signature: low profile, silver finished, and floral engraved, over a fixed walnut stock with the lines Beretta has refined across generations of the 686 family. As an over under it carries a round in each chamber with instant choke selection between them. Combo sets like this are the practical answer for shooters who would otherwise buy two shotguns one gun to fit, one trigger to learn, two gauges to enjoy. It is also a smart way to start a young shooter on the 28 and grow into the 20 without changing anything about the gun mount.
