Considering that a self defense shooting will take place, or maybe better said SHOULD take place up close and personal. Likely 20' or much less --------
---------if you can get your shots into a saucer sized area, and do it rapidly, that is all you needed. Almost all firearms with almost all ammo will do that.
What your CCW firearm does at 50' or 25yds is totally un-important as you are now, in almost all cases, well beyond the self defense distance.
