It seems logical that the Compact should shoot better - longer barrel, more weight, and thicker grip/controls. My Shield is the last resort for carry, and I'm confident I can put all 8 rounds center mass at 10 yards in a short amount of time. That's good enough to carry for defensive purposes IMHO.
Exactly, I think too many people get wrapped around the wheel with group size with a self defense weapon. As long as I can stop a threat at 10 yards, I have faith in the weapon. You don't need to put 7 rounds in a 2" area unless you're being attacked by a broom stick.
