Well the original design has served me well for almost 40 years.
My opinions are based on real life usage not internet articles.
My opinions are based on getting over-rated 1911s to work based on 20 years of experience getting them to feed truncated cone HP and shoot good groups without modification. I wasted good money on them because of magazine articles.
I shot first place in my class in my first IDPA match and shot many plate matches.
The problem was not me.
