Not sure whether this is technically the proper place for this question, but the Springfield Omega is supposed to be a 1911 model... of sorts.

Anyway, my question is whether I will run into trouble if I attempt to run 9x23 through a 38 Super barrel in the Omega. The 9x23 is a rimless cartridge, and the 38 Super Omega barrel headspaces on the case mouth, not the case rim, so I am wondering whether it will be OK to do this(?) Case length of both rounds appear to be similar (.9) and OAL is pretty close (+/1 .002); the only difference in dimensions is that the 9x23 has a slight taper whereas the 38 Super is cylindrical.

The Omega was designed to use interchangeable barrels, including the powerful 10mm, and the 9x23 has a pretty strongly reinforced case, so the question is whether this is something that I can try. I am interested in seeing the performance through the 6" barrel of the Omega.

Thanks for any insight.

I wouldn't recommend it at all,completely different set ups there,just because they're close in size doesn't mean they're interchangeable. A shortened version of the same caliber like 38 special out of a 357 magnum sure,but 1 headspacing on the shoulder and the other the mouth are 2 different things,plus the operating pressures may be a lot different. That's just my opinion though,I don't trust the "hey wonder if it'll work" when it comes to guns.

Squirrelhunter is right. I shoot a 9x23 Winchester in a rechambered Range Officer. The chamber pressure on this cartridge is a lot higher than a Super. Same as a. 223 as a matter of fact. They're close in dimension and some people shoot them in Super barrels but it's dangerous.

Hi Squirrelhunter & Burris101,
Thanks for the advice. I will pay good attention and keep my 9x23s to the Colt, which was designed for it!
