I have owned a 1076 for about a year now. I have only carried it a few times CCW because the thing fully loaded is a brick and doesn't help my back much.
On the question of reliability, it has eaten everything I have fed it. I have shot Remington FMJ, American Eagle LRN, and Federal Hydra-Shock's through it without any problems. I now use Double Tap ammo loaded with Gold Dots and love them too. The nice thing about Double Taps is that they are loaded to the original 10mm loading instead of the "light" 10 mm loads that are loaded today.
