I need to add a point about holstering your weapon after the incident. Many years ago when I started, we would do our standard qualification at the 50 yard line and work our way towards the 3 yard line. The common (bad training) factor was to draw the weapon and fire X amount of rounds for that distance, do a quick 'cover' and reholster. It was bad training because the reholstering was part of the timed course. So the covering was a quick shake of the gun and then a race back to the holster.
Nowadays we shoot a different amount of rounds at various distances to the target...or targets. And the covering is not part of the timed course. Thus we stress that you never holster the weapon until you feel the situation has been completely resolved and the threat is no longer present. In our simunitions training the cover portion might be a few seconds to 15 minutes (awaiting back up from a place of cover). We never rush to get the gun back to the holster. We scan the area for additional threats and only holster when the situation is safe.
This keeps in mind that we will likely be under duress and reverting to our training. Thus it prompts us to continually be aware of our surroundings before, during and after an incident.
Again, just points to ponder.
I just finished 80 hours of firearms training in the local academy yesterday. I qualified as top shooter in the class, and I'm by no means a distinguished shooter. I never took the time to think about why the strings of fire were sometimes so different. Three rounds on one target, three on another, one on each target, two on one target, etc. I guess it makes sense, mix up the number of rounds so we don't build a memory on one particular number of rounds.
We were, however, instructed to raise our hands if we had a malfunction. I experienced one, and cleared it and tried to fire my last shot before the targets turned away. When I couldn't get the shot off in time I raised my hand. Also, our timing did not include reholstering. The targets turned and we drew from the holster or punched out from low ready, and fired. After the set amount of time the targets turned away. When you finish firing, you cover scan and reholster.
