I ordered a Eotec for one of AR-15s. I read a lot of reviews and it was the highest rated for the size I was looking for. My wife has a laser on her 9mm. I might just get Trijicon sighes for my 1911 and for my AR. My wife is right handed but left eye dominant. I'm just getting everything prepared for either the economic colapse, which will eventually happen. Or for a rogue nation exploding EMP bombs about the US with the resulting power outage and zapped electronics. Congress was, about 5 years ago, going to spend about $200 million a year to get our power grid EMP proofed. Don't know if that has started or not. I think all vehicles manufactured or with refurbished electronics have them protected with grounded Faraday cages. The Trijicon doesn't require batteries, and should be EMP proof.
The above two are what might happen that to me would be the most devistating for all. Drought, hurricanes, tornadoes, vocanoes, earthquakes, will generally all be more localised. Hurricanes can be prepared for. Drought can be prepared for. Hungry desperate people, especially with entitlement mentality, will not know how to cope.
During the Great Depression things were far different. 40% of Americans still lived on farms, so even people in the city had relatives who provided them with some food. People were more polite, and more God fearing, thus more respectful. No one depended on the government for bailouts of any kind. Today most are not God fearing, nor the younger generation as respectful. More are dependent. Thus gangs can form to take from the ones who prepared.
Off my soapbox.
