I have a Dehaan 28 Gauge side by side which was manufactured by Huglu. It is my rainy day grouse gun and one of my favorite shotguns in the dove field. It has been a great performer. Overall I would give Huglu shotguns good marks. They can be a little crude and some a tad clunky but over all they are solid well built shotgun.
Something to be aware of when purchasing a Turkish shotgun you will get hit hard if you decide to sell it down the road. They just don't bring much on the used market. If you're buying that is plus; buy used and let someone else suck up the depreciation.
