In the Marines we all adjusted our gun to our sighting plane. That is why we have adjustable sights. It goes for rifles, shotguns and handguns. If you have groups that are 2 inches low adjust accordingly, This is one reason we go to the range to make sure that the gun we are shooting is aligned for ourselves. Any gun we use should be setup exclusively for that one specific user. It is nice when the sights are centered and all is pretty and symmetric but we need to have our equipment adjusted for us when the situation demands it.move the sight...fixed
Only if its off when shooting from sand bags or a rest should to adjust the sights.
I would not adjust the sights on my gun for Massad to be able to shoot my gun, I would keep the sights right where I shoot them. I would seek to find out if I were doing anything wrong in my grip, sight picture or stance and if then I find that I was now shooting where my POA was not the POI, then I would adjust my sights so that I was not shooting where MY POA = POI.The position of the sights in the slide is not sacred, on that we agree. My XD40 shoots POA=POI with the sights as they came from the factory, but if Massad Ayoob shot my gun and said it was shooting left, I would move the sight and try to figure out what I was doing wrong. Probably even pay him to tell me.
I am a very new IDPA/USPSA shooter. If I cannot shoot right and left handed with the same pistol, without making a six-inch adjustment, then I will not hit some of the targets at all.I push the sight over to the right until my group comes to center, and I call it good.
Group prints exactly where I'm aiming.
If I have to shoot with my left hand, I know I have to aim about 6 inches left of where I want the bullets to land if the target is far enough away that I need to use the sights to guarantee a hit.
