I've seen some 1911 manufacturers selling "hard ball" models. They say they're made for DCM competition, but both will shoot the same ammo. Some have solid triggers, some have triggers with 3 holes, and I can't tell the difference in the grip safeties, but they say they're different. Can someone please explain the difference, and how do they compare to the same maker's "tactical" models? Any help here? Wanna kill these ads? We can help!
