Some will give me a hard time for saying this, but it has to be said. There is a major safety violation in MontanaBigHorn's video. Every time he presses the slide back, he is muzzling his left hand. Worse is the position of his trigger finger on his right hand. I can't see it very well and I believe it's not on the trigger, but it sure is close to the trigger.
There is definitely a case in the chamber and it is probably a live round. This is a combination for disaster. He probably wouldn't kill himself if he shot his hand, but I've been told it hurts. So, please don't do this.
To move the slide back to do a chamber check, do it this way:

Sorry if this sounds like I'm being overly picky, that is not my intent. I just want people to keep their fingers on their hands. You have to violate two of the four basic rules of safety to hurt someone. The earlier video violates at least two.
Back to the regularly scheduled topic.
