I just pcked up a sxs 12g from a military buddy of mine. He bought it in Turkey when he was stationed there. It's a Huglu and has double triggers. I really like it and it shoots good. It has fixed mod and full chokes. I know all about the Huglu shotguns but I do have one question. There are very few markings except serial# and makers marks. There is an 870 mark and a mark on one barrel is an 8 and the other is marked 89. There is no chamber length marking. I took the barrels off and slid a 2 3/4" shell in one and a 3" in the other. They both fit flush in the chamber. Does this mean it is truly a 3" chamber. My buddy said it was but I don't want to take any chances. Thanks.
