I don't think this is addressed often, maybe because its obvious, but how do you guys do it?
I've always been taught to point in a safe direction (into a sand-barrel, preferably), dump the mag, rack the slide and watch the round hit the deck. Then check for clear.
I guess the other common variation is dumping the mag, then racking the slide with your palm over the ejection-port, capturing the round. Or racking in a fashion that results in the round flying out, then catching it.
Comments, thoughts?
