Why doesn't anyone offer a 357Sig AR pistol?

[ABNAK]

Can't find one for the life of me (using Google at least). Lone Wolf and Quarter Circle 10 have them on hold. Anyone know of one that functions well?

I think the 357Sig would make an awesome little PDW-type weapon, and an AR pistol format would be awesome.

I think I remember reading about a gas 357 sig AR a few years back, but I can't find it now.

There is the "Just Right Carbines" version as well as the TNW "Aero Survival Rifle/Pistol", but they aren't true AR's. They look AR-ish but they aren't.

What mags are out there in 40/357 that are adaptable to the AR magwell?

Glock mags are what has been used from what I've read. Pics I've seen are dedicated lowers built for the Glock mags.

Considering that the terminal ballistics of the Sig .357 is approx equivalent to the various 9mm offerings in JHP, and there's no lack of 9mm ARs, I'd think that would be the way to go no? Less expensive ammo also being a + I'd think. Anyone make a 10mm AR pistol?

The TNW Aero Survival Pistol (or carbine) can be had in 10mm.

Reason I chose 357Sig is at the higher velocities it should shoot flatter than a 9mm and probably a 10mm too. While the bullets in 9mm and 357Sig may be similar the terminal ballistics of the Sig pull ahead simply because of the velocity.

Considering that 124gr. 9mm will shoot to POA at 100 yards out of a 4" pistol, how much flatter do you need?

Availability of ammo is certainly an issue. For me, the larger problem is reloading. The bottlenecked .357 Sig case has to be treated like a rifle cartridge, including trimming and lubing.
Just too much trouble if you're going to generate a lot of ammo; might as well be messing with 5.56.
Interesting hearing from the merchant mariner, and pirates off the coast of North Africa? Is there nothing new under the sun! Cue the Marine hymn.

A correct pressure 357 Sig load (not the watered down store bought stuff) should outrun even the best 9mm +p. Before I get flamed, I'm on the road and can't look at my load books...
