I have an XD as well, .357 SIG. Great little cartridge with plenty of power, I am about to do some hand reloads to see what results I can get.
My main recreational shooter is a Springfield 1911 operator, early model with full length light rail (similar to TRP operator). Mods include: Chip McCormick grip safety, Wilson combat tapered barrel, Wilson trigger, all Wolf springs, hand fitted slide, etc. Really trick gun and eats virtually any ammo I throw at it. I'll check out xdtalk.
