Much like Glock’s adventure with the .45 GAP cartridge. The idea was sound and it made sense but trying to replace something that’s been established and loved for 100 years and is still outrageously popular is nearly impossible.

It would be on the order of designing a brand new railroad train… engines and cars, all of which might be better than what’s used now but requires a set of train tracks that is 2-1/2 feet wider than what’s used now and since the 1800’s. You might have invented the greatest thing since sliced bread, but it has a snowball’s chance in hell of ever coming to life.
