4Seventy,
As handgun hunting or self defense with one is Verboten in your neck of the woods, you might want to look at the Marlin Guide Gun. I really like mine, so do my kids as they wouldn't let me use it for deer season, they took it!

I've even seen a back scabbard for it that is really just a big holster. At six and a half pounds and holding five rounds of .45-70 or .450 Marlin it's a pretty potent little gun. Add a larger front sight and a ghost ring rear and you should be good to go on most critters.
