A few moons ago we were mentioning shotguns and I told you of my "cabin" gun. My Stoeger coach gun that I put rifled sights on. You mentioned you would like to see such an animal, well... here it is.
Double triggers so she is fast for a second shot and fast for switching barrels. It also has extractors and not ejectors which makes for quiet load changes if need be. The rifled sights are set up for the left barrel and I can throw a 1oz slug into a pie plate all day long at 100yards. I use it for filling the pot and for black bear getting if need be. It allows me to change loads quietly and covers all the bases.
So far... many ducks, a few porcupine, a feral turkey, untold numbers of tree rat vermin and one stubborn black bear who did about a grand in damage to various things around the yard have been taken with this setup.
