Get into 230 grain bullets and the game changes. At standard pressure for both rounds velocities are equal. Load the ACP up to +P pressure (same pressure as GAP) and the GAP doesn't have the case capacity to keep up when using 230 grain bullets. That's a fact, Jack.
Now you're talking 45 ACP+P, which is a nice sleight of hand trick, but you're still wrong. While most ammunition manufacturers don't push the GAP to ACP+P levels in 230gr loads, a handloader can do it pretty easily. See here:

Glock commissioned Speer to engineer the .45 GAP to put .45 ACP firepower into a 9mm frame. Glock's largest competitor at the time, Springfield Armory, engineered their frames & mags to put more rounds of .45 ACP into the same size grip. How is that a Red Herring? It's completely relevant to the discussion.
It's a red herring because your point is a distraction and doesn't illustrate ANYTHING relevant to the discussion, which is "What advantages does the GAP have over the ACP?" Just because Glock's GAP offering (supposedly) doesn't maximize the advantages does not mean those advantages don't exist. Plus, even in your example, the 38's grip circumference is smaller than the XD's--so you STILL lose the argument even when using your own examples.
That's a nice theory, but no one has actually engineered this perfect .45 GAP pistol you theorize. Here in reality .45 ACP pistols still have the same or more rounds in the same size grip.
See above. Still irrelevant even if you were correct (which you aren't). 45ACP pistol in your example has a larger grip than the G38.
Not at all. If you can't readily get ammo from local sources it's time to consider handloading. If guns in the caliber aren't readily available, then we don't even need to worry about ammo do we?
Maybe you'd have a point if your point were grounded in reality. It's not. GAP pistols and ammunition are "readily available". Practically anyone in the US can have a GAP pistol and ammunition within a matter of days even if their local shop doesn't stock them. Bud's Gun Shop, GalleryOfGuns, Impact Guns, etc etc. stock GAP pistols. GAP ammo can be found practically everywhere.
Clearly until you get into heavy bullets. If you want to nit pick your favorite bullet weight then maybe it's superior. If you want a CLEARLY superior auto pistol round Norma invented it back in 1983.
Up to 230gr, the GAP is better than the ACP hands down. If you start talking ACP+P vs. GAP, they're on an even playing field, but the GAP is still a shorter round. It's simply a better cartridge in almost every aspect, PERIOD. The ACP is over a century old, it's not embedded with magic. I don't know why people can't shake themselves of this notion.
As to the 10mm, no arguments here on its superiority.
KOOLAID oh yeeeh....
