That velocity seems to stir up the old "might as well carry a .40 S&W" argument. Underwood and possibly other companies load this weight in 10mm up to a reliable 1250fps:

Yeah, lower recoil is nice but it also provokes the same argument. I like .40 S&W. I use it to do .40 S&W sorts of things. If I was going to spend the cash on a 10mm pistol and ammo, I'd want it to do 10mm sorts of things.
Yep.
That's why for years the hardcore 10mm fans have said: if all you want a 10mm pistol for is to shoot only (or mostly) '40-level' loads, DON'T get a 10mm. Get a .40 pistol and be done with it.
Why waste your money on downloaded '40'-performance from the more expensive 10mm case? Just stick with the .40 cartridge.
And although you can load or find 10mm ammo topped with all the same bullet-weights as the .40S&W, where the 10mm really shines - velocity-wise - is in its ability to push the 'heavy-weights' very fast ... starting at 200gns and up.
Especially with the advent of 'Glock-friendly' polycoated hard-cast slugs (slick to feed, and no leading up the barrel). You can load 220gn 10mm HC slugs to 1250fps, and 200gn HC slugs to 1275fps.
Try doing that in a .40 pistol and you get a hand-grenade.
