As I stated before, I have carried some nice guns (even though I don't have much money) just because guns are a big part of my life. On the flip side, I have met people through the shooting sports who are now friends of mine. Some of them have thousands of dollars of disposable income every month. They drive BMWs, take expensive training classes, go on very expensive vacations, and pack pistols that cost more than I make in a month. None of them have ever indicated to me that they thought the quality of their carry gun would give them an edge in a gunfight. They just like nice stuff and they can afford it.The point I have tried to make is that some who buy the most expensive guns seem to think that somehow that - in itself - will insure they'll come out on top if they get involved in a confrontation.
Frankly, I reject your entire notion because I think the "some" you are referring to is such a small minority as to be insignificant.
