When you live in a place that outlaws standard capacity mags, it's prudent to practice and be prepared to perform tactical reloads.
I'd rather have one in the chamber when I drop the mag for a reload than have an empty chamber and locked back slide.
Of course, what I'm thinking now might go out the window in the adrenaline-drenched events as they unfold.
I too thought this as well, but ASP has reviewed thousands of vids and have yet to see any kind of reload or maybe like 1 of thousands. And the most rounds fired in a vid was like 8. But the average from all the vids they reviewed is about 5-7. He had a vid about this a year ago or so. Guess no one used a G43 that only carries 6 rounds.
I'm sure there are people out there who had to do some kind of reload, but ASP reviewing thousands over the years would be a good source of info if you don't want to go looking for yourself. The hard part is that the vids often don't go into what kind of training the good guy had. Only seldomly is he able to interview the good guy as well. If it were me, tact reload would be on my mind as a thing to do once all threats are neutralized.
Even BJ Baldwin who went 10 for 10 hits didn't reload (he probably had a 15rd mag since this is Vegas). He got in his car and dug out asap because he didn't know if there were more people. He drove like a mad man to his brothers home on a flat tire.
Going off topic here, but even the quick "scanning" left to right is BS. People do it way too fast for their brain to even pick up what they're looking at. John Lovell (Warrior Poet) explained this. He has a phrase he says. Scan left and say "Does anybody else want to play". THen scan right and repeat "does anybody else want to play". Then look behind left and say "Did he bring any friends". Then look behind right and say "Did he bring any friends". Then look back at the bad guy on the ground "Make sure he's still down". All said in a normal rate of speech. He states that this is the fastest his brain can scan/comprehend visuals. Anyone doing the half second left to right is just going thru the motions.
Of course this is 1 mans philosophy, but I did a drill with "scanning". You place various papers (8x11) around you on the wall with big numbers or letters on them in a random order. Have a friend call out a number/letter and you have to find it. It took me longer than the half second scanning of side to side for my brain to process the info. At 1 point a number was called and it took me like 20 seconds to find it. I thought he was screwing with me and that number wasn't posted. All this was done with the pistol at the ready position.
John also mentions tunnel vision. He did a class and spoke to a SWAT officer who responded to a shooter in a supermarket. The officer swears he pulled the trigger multiple times. But the guy didn't drop, nor did he hear any bang or flash or recoil of his AR. So he went behind concealment and did a malfunction check. When he peaked back up, the bad guy was on the ground dead. So this SWAT officer did fire his rifle multiple times, but tunnel vision set in and he didn't feel/hear anything. No one else shot the guy.
