I found the videos intresting because I've never trained Krav Maga from a school. I looked up the unarmed vs gun techniques on the internet then started drilling the material using a paintball pistol and paintball goggles. The krav maga works well when the pistol is within arms reach. But for distances 5 - 8 ft I had to come up with my own techniques. I've gotten very lite on my feet. The average joe, the first time they do this drill, can't score a hit with me starting 8ft away. By the time I close distance they usually only get two or three poorly aimed shots off. Then the gun is disarmed and I give them a nice couple shots with my fists or whatever. Once they learn that I have only two sides to really dodge to, left or right, and as they become better at shooting a moving target, it becomes easier for them to score hits. But I've never had anyone be able to hit me the first time they do this drill. That's why I think it has merit for practical application and if I ever find out, I'll let you know.

One question? How many here have worked in an environment where thye actually had to defend themselves often or had physical encounters? How many have had to apply what they already know?

In the ring is different. Rules, refes to stop the fight. Street or psych hospital? Only you can stop the fight or when the other ones beats you up senseless.
