Doc, you wanted to play with 357sig for cheap, here you go.
Quoting from

PistolGear Drop-In Barrel for XD
Details
The PistolGear Semi Drop-In Barrels are made to factory specification, with a few added twists. The dimensions are over-sized in a few keys areas, yet we designed the barrels to where they will drop into approximately 90% of the XDs & HS2000s out there (hence the name semi-drop in). Unlike the XD’s stock barrel which is carbon steel, our barrels are made from 416 stainless steel; the same material used in our “Match†barrels.
Note: If you have a Service model, the Tactical barrels will fit your gun; however the barrel will extend beyond the slide.
Note: This is NOT a conversion barrel!
Note: .357SIG and .40S&W barrels are interchangeable, meaning that you can convert your .40S&W XD to shoot .357SIG rounds by merely changing out the barrel, and viceversa.
