The Grizzly was available in several calibers including .357mag, .50AE, .45 WinMag, 9mm WinMag, and probably a couple of others that don't come to mind right now. But, like the Coonan, it's much larger than a normal 1911.
If you want .357mag power in a 1911 from factory ammo look at the 9x23 Winchester. If you can't find one you can convert a 9mm or .38 Super by fitting a 9x23 Win barrel to it. I have a Colt .38 Super with 9mm and 9x23 Winchester barrels, factory Winchester 124gr & 125gr ammo run at 1450+fps out of a 5" barrel. Not too shabby from a regular size 1911 with 9 or 10rd mags. And, if you handload, you can really work up some smoking hot loads.
No, that doesn't solve your ammo compatibility desire but it's as close as you'll get performance wise, since your only .357mag auto choices are the DE, Coonan, and Grizzly thanks to the length of the .357mag cartridge.
