Does not matter if they come from shooting sports, practice or training there are lots of training scars that people unintentionally do to themselves. Here is a list of some that come to mind that I see in classes and matches regularly. I have done most of these things in the past and I try really hard to no longer do them. I am working or getting them out of my normal procedures. Working to be better. Please feel free to include your own observations.
1) Finish shooting and immediately re-holster. Putting the gun back in the holster is part of the drill or sequence.
2) No scanning. Ever.
3) Not topping off or reloading even in circumstances where allowed.
4) No follow through on the sights.
5) Lack of trigger finger discipline. The finger is inside the trigger guard when it should not be.
6) No ammo left on the body to use.
7) Taking the gun off to go home or to lunch. (WTF)
8) Not having ammo on the body on cold ranges.
9) Shooting faster than they can see the sights lift. Which means faster than they can stop if the threat is stopped.
10) Muzzle discipline goes out the window they first gun problem that is encountered.
11) Doing administrative reloads and press checking at the belt level.
