Dahermit, no, that's not quite what I'm saying.
In any dynamic shooting, stance and grip are continually being modified, even if only slightly. What should remain constant is front sight tracking, and that is accomplished through trigger manipulation and focus (focus through observation, not to be confused with concentration). Your objective should be to produce consistent trigger manipulation and front sight tracking regardless of stance or position/movement.
As our bodies change, with every round that we shoot, we should be observing and learning. That means our "technique" is constantly evolving. What works for the new shooter won't necessary work when they are ready to shoot IPSC. Likewise when they are suited up to raid a drug house, those IPSC fundamentals won't necessarily all translate. Even if you aren't going from application to application, if all you do is IPSC or range work for HD, you should be open minded and flexible to allow your stance to change otherwise you will always limit your performance.
And these ideas aren't all my own, I have borrowed them from the greats. If you listen and watch some of the better shooters of our time (Brian Enos, Rob Leatham, Todd Jarrett, etc.) you will find these same ideas being consistently repeated. Open yourself up and allow your shooting to grow the way it naturally is inclined to do.
Don't get me wrong, being comfortable with some basic elements of stance and grip are certainly important, especially for the beginner, if for no other reason than safety, but also to provide a sound foundation to work from. This is why I suggest that new shooters who are interested in developing their shooting spend a little money to get training from a quality instructor.
One point of clarification.. sight alignment and front sight tracking are distinct things. I believe (some agree, some do not) that even (active) sight alignment isn't ultimately all that important for dynamic pistol shooting. With practice and a solid index, by visualizing the front sight, your sight alignment has taken care of itself because of a well-developed index. On the other hand, visualizing the front sight's movement immediately following the trigger break is absolutely vital to placing rapid follow-up shots. And the motion of the sight is irrelevant; it can go straight up, it can go to 2 o'clock, it can do a figure 4, but find what it does and watch it intently (the value of both eyes open). If it doesn't do what you expect it to do, then it's telling you what's wrong with your shooting while you're shooting, so you can correct for the next break. "Heady" stuff I know, but worth putting out there.
As the shooter matures from beginner to intermediate (which usually happens pretty quickly), I think there is benefit in not being hung up on techniques or equipment, as people are prone to do in whatever field they are in (photography, fitness, shooting pool, golf, etc.). Perhaps the only area where people don't think better equipment or supplements or "pro secrets" will actually make them better is chess. haha What I'm driving at is, work on the shooter. Shooting isn't a very difficult task, allowing your body to naturally perform without becoming tense from excessive thought is the largest hurdle.
