These things appeared on the market almost 10 years ago but I've still yet to see one in action.

12-76 and 9,3x62 would be a potent combo for most game short of Elephant!

Looks an interesting beast. Being a pump action it would illegal in the UK - pump action rifles are prohibited.

Being German it will be well made. Looks quite heavy and how well it balances cant tell at all. I would suggest it probably balances more like a rifle than a fine shotgun. Shot barrel will be good for foxes or pigs using slugs / heavy shot, you could shoot a phaesant with it, but it would n't be like using a good shotgun.
