I was thinking I would want something very reliable that I could readily find ammo or spare parts for, so here goes.
Glock 22c for every day carry. With 9mm conversion barrel for types oh shit situations when .40 gets hard to find.
M1a in one of the shorter barrel configurations, probably topped with an eotech for general use and the 3x magnification tube for longer work. Would also work well for taking down medium sized "dinner" animals.
mossy 500 with both a 18/20 and 28 inch barrel. Can be used for devistating close in work, and great for medium ranges with slugs. Plus it can put dinner on the table.
So far the only one of these I would need to acquire is the m1a. If I needed to, I would gladly substitute it for either my savage 111 30-06 so I can still put food on the table, or my ar (which wont be as good for hunting, more for SD).
