It turned out things like the XD .45 and the 21SF were "not too chunky" for most people so the market just skipped all this mental masturbation and went back to the normal cartridge.
Springfield had .45 GAP XD pistols too (with metal mags, BTW) which were possibly in your wheelhouse, all of which failed HARD commercially, just like Glocks, so it wasnt for lack of an attempt by at least one vendor. It didn't matter, nobody cared, that wasn't a big enough of an advantage to get someone to buy that over a diet .45 ACP handgun that took normal ammunition.
It's not intrinsically better it's literally that it's normal and .45 GAP is not.
You're making an argument for a cartridge based off a fairytale. (that 45 GAP would ever be economically viable, which is impossible. ) price and availability is pretty important.

If the ammo is too expensive and hard to come by, people arent going to buy it.
Whats next, are you going to tell us you could have changed the market if you had a time
machine? I could change a lot of things with a time machine.
