I’ve read a lot about what kind of SHTF gun you should have and I only seem to come across the debate between an AR or an AK47. I never hear about the versatility that a shotgun has such as the Mossberg 590 or similar. To be realistic if a SHTF scenario were to ever happen I highly doubt that any of us would be on the front lines so why not consider a shot gun. With the newer slugs on the market and better shot why not. Opinions.
