I'm not talking about group shooting either. But my practice is for compitition, and not really defense. Although I imagine the skill will transfer over a bit.
I look at like if I see my sights, I can call a miss then make that shot up. If I don't see my sights I can't do that. Is it really that much slower to see something that's already there? Just watching what's happening in front of you shouldn't take any longer to do.
In my training, I try to see my sights for every shot. Even more so in dryfire. I don't see any benifit to not seeing them. Now on game day I will break some shots with out seeing my sights, although that's really not the plan.
If you are breaking shots when you arent planning to you need to get your trigger finger under control.
Blaster, correct me if Im wrong, point shooting is a target focus shot. ie your body alarm response causes your focus to jump and fix on the threat.
