Armed Culture did a great little post on finding good gun advice, and I like this part in particular:
The four factors of expertise
#1. Breadth of experience.
A guy who has one brand of wine that he drinks is not a wine expert, even if he drinks a lot of wine. Taste only comes with broad exposure. When someone tells you that a product is good, always ask, “Compared to what?”
The typical gun reviewers who lack in this area are military and competition shooters. Many servicemen have extensive experience with the weapons provided to them by the government. But they know little to nothing about the wealth of options available in the civilian world. If your dad got you into sporting clays as a kid, you might be an Olympic class shooter… but that won’t make you an authority on handguns or rifles, or even hunting shotguns.
After reading that, I realized why I was going for “a mind of many things” approach to my journey through firearms culture. I will listen to anything that Rob Leatham or Angus Hobdell have to say about USPSA, but I wouldn’t go to them for rifle advice. In the same manner, I know people who can bust clays with just their mind (and a shotgun), but know diddly about handguns.
I want to know enough to speak rationally on most gun topics, and I want to be good enough so that when someone says “Hey, do you want to go shoot (insert name of firearms-related activity here)?”, I know I’ll be good enough to enjoy it and have some measure of success at whatever it is.
As I’ve said before, life is too short to shoot just one gun.
