Gotta disagree...I have two, a Kimber and a Dan Wesson that will shoot anything I feed them.
And..
The article was about military firearms with the longest history of use....I believe the 1911 is 70 years or so.
Kimber and Dan Wesson are 2X-3X cost of most new handguns. New overpriced 1911 have throated chambers to feed HP and lose critical case support. Also, many new 1911 designs have upgraded coil spring extractor like new designs.
A number of new 1911s have feed ramps integral with barrels. There are two major problems John Browning fixed on Hi-Power design.
