The STI Eagle 5.0 and Eagle 6.0 2011 pistols (not to be confused with the Desert Eagle pistol) will be offered chambered in .357 SIG.
According to the latest STI newsletter, they got a lot of request for this caliber at SHOT Show ’09. I am surprised, I did not know that this round was that popular. The .357 SIG was developed in 1994 to replicate .357 Magnum performance in a rimless case suitable for semi-automatic pistols.
