“The 1911 is an obsolete relic that must have the original design butchered to feed hollowpoints.”
Uh huh. Better tell that to the dozen and a half manufacturers still using the 1911 design for the weapons they continue to make. By the way, if you have any of those obsolete relics you’d like to unload I’ll be happy to take them off your hands. And I won’t charge you a penny!
Manufacturers make WWI technology like 1911 and V-twin motorcycles for the nostalgia market. There is a huge number of people willing to overpay for obsolete technology, so manufacturers would be foolish not to supply to that market.
That does not mean that the 1911 and V-twin bikes are as good as modern designs.
A throated 1911 chamber has case support removed, making it weaker than a modern design with the feed ramp integral to the barrel. The leaf spring extractor incurs much more stress per unit of deflection than a coil spring and will not last near as long without having it adjusted.
