Not a bad article.
I'd have to politely disagree with one statement.
"If it's comfortable, you are doing it wrong."
A gun must fit YOUR hands, and be comfortable in YOUR hands or you will have issues with recoil and accuracy. Canting the gun isn't a big problem at close distances,, (under 25 yds,) but if you cant the gun and try shooting at 100 yds,, (or more) you will suffer in the accuracy dept.
But I do accept that for the purposes of the article,, and the use of small handguns for EDC, & SD, it can work ok.
