Congrats on getting a BSS. I have an early one - assembled in Korea from parts made in Japan, with a silver, single non-selective trigger. Originally choked F/M, now M in both barrels. I have used it for a few 'traditional' duck hunts with Kent Impact shot; it certainly does the job over decoys.
It is a heavy gun, very stoutly built, but I have always liked the handling since I tried one belonging to a friend. The previous owner fitted mine for a sling, which helps when upland hunting to offset the weight.
Discovered I really like it for late season clean-up pheasant hunts on Pelee Island, when we shoot more powerful loads since the shots are farther out then. My buddies christened it "The Howitzer" for its long reach......
