To me, having self-defense gun skills means in addition to conscious, slow-fire, deliberate marksmanship, you can run the gun at faster speeds, requiring unconscious operation — while still hitting. Mastering static, slow-fire marksmanship isn’t all that difficult, but shooting fast(er) is hard. This is in no small part because you can’t think your way through the shooting. This kind of unconscious, reasonably speedy fire will be called for in a self-defense situation. I submit you have conscious marksmanship reasonably down pat if you can hit an 8" or 10" plate at 25 yards almost all of the time once your gun is zeroed. Which is not to say you shouldn’t try to improve this by adding speed.

With regard to faster shooting, all of the following criteria are subjective, and reasonable people may — indeed, will — differ, and it assumes you’re using a full-sized handgun. You’ll need to make adjustments for smaller guns.
