We've got a few shotguns. Mostly sporting guns so side by side or O/U's in 12g and .410. Theres a bolt action Webley with a 3 round magazine which takes the 3" magnum .410 loads. Thats a great rabbit gun but not really tactical lol..!
The most tactical type weapon we have is a Beretta A390 semi auto. Its also a sporting gun but its chambered for 3" 12g Magnum rounds so it really does pack a punch!
I also have an old Crimean War percussion cap musket rifle. Again, not tactical but pretty cool hehe!
