I still have my old 1200 12 ga for 2.75" shells and 30" full choke barrel which I bought new back around 1981 or so from the local Cr@ppy Tire store. It's been used for waterfowl hunting (back when I did that), for trap shooting, and even for upland (used to have to let the grouse get a fair distance from the muzzle so they didn't disappear in a mist of red and feathers with the full choke and long barrel).
Never a fail-to-load, or an FTF, or a fail-to-eject. I just need to trim up a new grind-to-fit recoil pad on it when I get some time, at one point they had pre-fit pads available, but those went off the shelves 15 - 20 years ago.
I keep it as a back up in the vehicle in case my SX3 somehow falls ill while in use at the trap range, or while out for grouse, saves a long drive home cursing the whole way. The old fixed full choke barrels don't take kindly to steel for duck hunting.
