I have yet to shoot a completely inaccurate gun, I think most guns are inherently accurate but it is your ability to be accurate with them, does the gun work well with you or not. That is when the trigger, sights, and ergonomics comes into play. Yes I can shoot cheap guns well, yes I can shoot small guns well, and I have out-grouped scoped hunting rifles with my ak47. If the only knock on the sigma is the trigger, well that is easy enough to fix in my mind.
