Article made some good points. I've heard similar "opinionated" comments at gun shows coming from seemingly "experts in thier field". Unfortunately, newcomers to the shooting arena do not take the time to do some researching on their own and sadly rely on the bad advice from one of these so-called "experts". I get the point that a woman walking into a gun store looking to purchase her first firearm would take it that the person behind the counter would/should know what they were talking about and walk out with the advice given. I don't know the easy answer to overcome that situation other than to interject into the conversation to where you know the advice being given is bad enough to get a novice hurt should some future situation arise.
"If the topic in question is a barbecue recipe, advice on extracting wine stains from your tan carpet, or the best place to purchase scented candles, opinions may vary and bad advice is not that big a deal." ........so, I have this barbeque ribs recipe......a really good barbeque ribs recipe if anyone wants it.
