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.
