If you had to pick 2 fire arms for a apocalypse or a SHTF scenario which 2 would they be and why? Mine would be: 1. Springfield XDM .40 - Reasons would be the .40 ammo is becoming very popular since most PD's are switching to that caliber and it's not to expensive to stock pile but still has plenty of stopping power. 2. Remington 870 - Reasons would be, 12 gauge ammo will be very easy to find, great close-mid range stopping power with buck shot and long range stopping power and accuracy with slugs. Also the 870 is arguably the most common shotgun in America so it would be easy to find parts for.
