The irony that the TactiFools worship their blinged up Glocks with red dots and race gun 1911s, both of which use rounds that pre date WWI
Our military uses the M4 carbine which is a design from the 1950s , I qualified with an M16 in 2007 in Basic, my Dad qualified with an M16 in 1970 in Basic
"New" rounds like .327 Fed Magnum died on the vine, the FBI wanted 10mm , which evolved into .40, which also fell out of favor. .41 Magnum is a niche round , it once was supposed to be the "Law Enforcement "it" round " .
People want 9mms, .45 ACP, .357 Magnums and .44 Magnum is the "Dirty Harry gun" . The market stays with the bread and butter, guns just evolve around the same rounds.
S&W .460s and .500s were the "big
" guns of the 2000s but no one wants that stuff no
