IMHO - the 9x19 was a mistake that should never have come into being in the first place.
The tapered case keeps the round from living up to it's full accuracy potential without a lot of high dollar work done on the gun.
Witness the Sig 210.
& plase don't counter that the 210 has other things that make it as expensive as it is.
A 1911 in .38 Super Auto can more than hold it's own & cost a whole lot less & be every bit as nice.
If old George Luger had decided to put together a new cartridge from scratch, instead of blowing out the shoulder on the 7.65mm Luger, things would have been better.
He didn't and things aren't...
I'm afraid though, that given the huge investment in 9x19 hardware NATO has, it's not going away any time soon.
