As fear increases, folks will buy all of the ammo they can. Don't be surprised if the Federal government ceases ammo sales if any civil unrest happens. Your logic is correct, but you don't list an AR platform rifle in your list. If you really want to stick with 9mm, have you considered an AR-9, Scorpion or an MP5 (either H&K or PTR varients). I have two AR-9's and an MP5 with pistol braces. They are all so much fun to shoot.This convo started in LNC about buying ammo, here is probably more appropriate.
I think the run on ammo is starting. From when I first posed the question to having just ordered some ammo the 22LR I put in my cart is out of stock now and the 7.62 I put in my cart increased in price. Now should I add a new gun? Don't know if I want to go handgun or shotgun...I have a 92FS, G19, Shield, and .357 revolver. I have a Remington 12ga pump and 1200 (have not shot in probably a decade). If I go handgun I'll stick with 9mm as that is what I have most in stock. Damn decisions...
