There is something to be said by buying durable goods now before the value of your currency is inflated away. Ponder:
Revolver $300
100rds .38 $50
Basic holster and
two HKS speedloaders $50
So for around $400 you could assemble a solid basic self defense kit. You could easily make other choices to better fit your wants and budget.
Ruger Security9 9mm with two magazines $300
100 rds 9mm $35
Basic holster $20-35
Additional 15rd magazine $30
OR
Mossberg Maverick 88 12ga Two barrel kit $260
100rd 12ga #7 shot $30
25rd OObuckshot $30
Sling and swivels $20
Do I expect to make money? Outside of mad max/zombies! no.
Would I expect to loose money? If I bought new guns and am now selling what is now "used" that's possible. I have seen PANIC! pricing on the Ruger handguns from a local dealer at $450-500.
