Honestly I find a lot wrong with his suggestions.
The “hive mind” is often driven by add campaigns rather than anything objective.
“Online Reviews” are much the same.
If you’re going to seek advice the first thing to do is seek it from respected, qualified sources.
My advice remains pretty constant. First, identify a few quality manufacturers with excellent records for reliability in their firearms.
Second, based on your needs try several different makes and models out to find what fits your hand best and which you can shoot the most accurately.
What are the most important criteria for a defensive handgun?
A Reliability, it has to go bang every time you pull the trigger.
B Accuracy, you have to be able to hit what you’re aiming at. That is a combination of proper fit and ergonomics.
C Forget the rest, stick with A & B and you’ll have exactly what you need.
