Yes, practice point shooting at 10 feet. Nothing wrong with that. The reality is that an attacker might be standing beyond my wife, using her as a field-expedient shield. If I have only practiced point-shooting, I am going to have a problem. The reality is that my GSD* might well remember her heritage, and go for an attacker. If I have only practiced point-shooting, I am going to have a problem. The reality is that an attacker might be wearing an explosive vest, and saying something about Allah being great. If I cannot shoot him/her in the face, I am going to have a problem. If my attacker is using hard cover, and I am stuck in a fatal funnel, there is no X to GTFO, so I will have a problem.
I shoot an old-school PD qual; 20% of my shots are "hip-shooting," fired from well below the line-of-sight. Actually, I do not disagree with such a large percentage of our shots being point-shooting. I do disagree with the instructors who hold us to the elbow-against-lower body standard, as I prefer to extend the weapon farther forward, as taught/described by the late Bill Jordan, formerly of the U.S. Border Patrol, or to shoot from a high #2, as taught by SouthNarc.
FWIW, I really have shot an attacker, at the approximate distance I hip-shoot on the qual line. Did I hip-shoot? No. Did I point-shoot? Well, partly, yes, but it was, two-handed, arms more-or-less isosceles, looking over my GP100. Had he been painted to resemble a B-27 target, well, I hit the X, which concluded all hostile actions instantly. Had he managed to first grab one of the other persons present, and been using him as a shield, well, it would have been time to align the sights with my eyes, and to drop the blade into the notch.
*One is no longer relatively safe while walking a dog. People are being hijacked for their dogs these days. And, no, I am not going to shoot through my dog to nail an attacker; the search for a really good dog takes years, with some amount of trial and error.
