Defensive/fighting
Hits matter more than pinpoint accuracy... You want to hit where you are aiming, but its generally better to be fast and close, than slow and dead on.
Some teach double taps, or multiple hits. As long as you are hitting center of mass, with about a 6-8in diameter... and doing it quickly... That is good enough.
Practice can keep your shots to a smaller diameter grouping, which is preferable. Though I have seen an instructor say that if you are hitting shots that close... you should be shooting faster.
Those guys on youtube getting two shots off in half a second onto steel silhouette targets... looks and sounds impressive, but most of them are making hits with several inches distance between them, you can tell this when they use fresh painted targets.
The guys that do serious competition.... they can shoot quick and make smaller groups, but they fire thousands of rounds in a week for training.
Bullseye type shooting, which is shooting for the best group you can, is a different mindset, and how you train for it and the techniques involved are different, though similar in some ways.
Its always good to practice shooting for groups regularly even if you are more focused on practical shooting. As it helps things like trigger control, and focus. I always start my range session with a mag or two at a more leisurely pace. When my target/mind/muscles are fresh, and my body is at its calmest. One shot every second or so, no faster, brings my groups down to the 1-2in range depending on the distance and how I'm doing that day...
I could slow down even more, and rest after every shot or two, which keeps your muscles from being as tense and tiring. I can make some small groups that way... But I usually just keep at the nice one shot a second pace until the mag is empty.
After that I focus on shooting faster, in pairs, or more shots... sometimes I fire the whole mag quickly... Going for groups no bigger than 4in, though I do make a couple fliers sometimes.
Everyone is different, and how they train, their views on what is best... its all personal in the end.
Above all, I want to have fun while at the range.
