Glock 17 was the first variant, 19 came later. Forgot the Beretta 92 series. “Top Five” is subjective, based on author’s opinion. Lots of good and interesting stuff out there. Poly 80’s 80% lower is very interesting , owing to the fact that you can make it yourself.
Sig 320 is very popular since the Army’s acceptance.
I wonder why the Walther PPQ doesn’t get more good press.
