Firearms training has to be safe for firearms, it is never realistic. It can only be as realistic as possible. Actual fighting can and is realistic, bruises are real, being thrown is real. You can't get legally shot with a firearm during firearms training. Training has become big business, most I have seen is worthless. Fights take place in the time it takes to click a pen. There are no rules, except one, win, all parties want the same thing.
I have been to enough funerals, and been in a few scrapes to tell you, IT IS NOT LIKE TRAINING. Over a dozen attempted stabbings, only cut three times, minor. Won every time because I fought, I rushed and won, period. Most fights happen within three strides, IMO it is silly some of the training for things like malfunctions. If your weapon jams, MOVE, use the gun for a club, but either attack or run. Survivors fight, they don't play by rules, and they don't clear jams. Training to clear jams, unless you are a soldier, will get you killed.
But hey, each to their own, before I became a cop my father taught me young, fight dirty, fight fast, and WIN.
This has made me remember a incident with my father when I was very very young. We had a dairy, and dad was filling in for a driver. He stopped to check the route schedule and was approached on the drivers side by a young man with a knife. No hesitation he hit the man with ice tongs, and drove away, all within a split second. Had he went for a gun instead of those tongs, he would have been cut. There certainly was no time for clearing.
About 40 years ago a ISP investigator was pulled on the side of the road writing a report. One of the local pot heads rushed the car, and in split second leaped in the window and gutted him. He didn't even touch his gun, certainly no time to clear a jam. 20 years ago a female FHP trooper stopped a vehicle that had just robbed a video store between Big Pine Key, and Marathon. The male and female suspect had a female hostage from the video store. Before the trooper could react she was attacked by both and dragged into the woods. The only thing that probably kept her alive as they tried to get her gun is she kept her hand on it shoving it back in the holster, with a broken arm. Pure survival, but no time to clear a jam.
That is not taking into account the many videos that are out there of real incidents both police and civilians. Seems to me the civilians without training usually fared better, they just fought to survive. No gun to even clear a jam, and they survived.
It takes luck, determination, and a will to do anything to take the attack to the attacker. Clearing a jam is not going to do it. I have never heard of, or seen any, except for military, surviving by clearing a jam.
