No expert here - just someone that shoots a lot and has for a long time. I really like capacity more and more. I find it difficult to carry a 1911 (have 3 custom/semi custom) because of the capacity. I also have been practicing high speed shooting at close range ie 8 yards. When you can fire 6-11 rounds in one second and all are in the chest zone, high capacity makes sense to me. I'm not so sure that capacity may not trump everything in self defense carry. I also sometimes think that pin point accuracy is the enemy of defensive shooting. If I shoot slowly I can shoot about 1-2 inch groups at 8 yards. If I shoot 6-7 rounds in one second the group will be 6-7 inches. I suspect that the 6" group is better in a self defense scenario.
