I was tempted to put in a shotgun as well, but not so sure about a specific one. There's soooo many to choose from and as a class they're a very good weapon to have on hand - once the factory made ammo is all gone, the shotgun / blunderbuss types are almost certain to gain a huge following.
Not all that impressive Rae, you only beat me here by about 3 months. Mind you, there was that enforced and rather unnecessary period last year...
