Shooting the XR9-SC (Shorty Canadian - 4.2" barrel) today, I hit 2022 feet per second with RBCD 60gr ammo, with a muzzle energy of 544 ft-lbs. I also hit 1353 ft/sec (503.5 ft-lbs) with Black Hills 124 gr JHP - which beats the pants off anything Cor-Bon I have shot up to this point in time. This is the first batch of testing I have done with the full-length barrel and the proprietary production chamber.
