Anyone own the Sig Rattler with Arm Brace? I have seen one or two in stores and it sure fits the definition of super cool firearm but the 2000+ price tag keeps me from buying one. Does the short barrel effect reliability, how accurate is the rattler out to 50 or 100 yards, anyone come up with a shoulder holster? If these were priced in the 1200-1500 range I would be all over one but the last one I saw in the LGS was 2150 and far beyond my ability to afford :-(
