If you can't shoot a gun accurately slow-fire, you can't shoot it accurately rapid fire. Careful, precise shooting practice affects every other type of gun handling.
Absolutely! If you dont have good basics and "properly" ingrained skills and cant shoot reasonably well, speed isnt going to help.
All shooting that we do at the range is low stress, whether slow or rapid fire. There's never a threat of bodily harm from a target.
This all depends on what type of practice your working on. There are some forms where there is bodily threat from the target (usually minor, but an active threat all the same), and there is a good deal of stress.
Sometimes you learn more with what appears to be a toy than you do with a real gun.
As far as shooting slowly in a SD situation is concerned.....is that a necessarily bad idea? Common practice for SD seems to focus on different forms of rapid fire. Why is that? After all, one precise well placed shot is all that is needed. (I know that it is far easier to write that than it is to do it, but still...)
You have to shoot at the speed and distance of the encounter. If time and distance allow, slow would be better, just do it quickly.
While one well placed shot is all thats needed in a perfect world, things are not that simple in the real world. That one well placed and deadly round, may take time to work out, and you too may well be dead at the end of it, if you dont continue to shoot until the threat is down and done.
The only right answer, is to shoot the target to the ground, and that takes whatever it takes.
My .45's and other pistols (and my rifles and shotguns) are used far, far more frequently for competition and hunting than for combat. Those two viewpoints influence what is a "waste of time" and what isn't.
Most of mine are too. For me though, there are more than just "two" viewpoints, and some of us continue farther into the abyss.
While there is a lot to be learned from them, you can only get so far with paper targets and basic forms of practice. I've learned and developed more in a couple of years of "playing with toys", than I have over the past 45+ years of constant practice with the real things. None of the "real" time was wasted (well, some of it maybe
), and a lot of it carried over, but a lot of ingrained "skills" needed to be adjusted or modified, and you would never know that if you didnt have a target that was actually trying to kill you just as hard as you were tying to kill it, and not just standing there waiting for you to shoot a nice little group into it and get a score.
