I'm not sure what you call it. I think my terminology in my originl post was incorrect. I just grab the rear of the slide (over the top) and pull it back. Think of a shot gun shuck only on the top of the slide.
Take a look at this Todd Jarret video, I use the third method....

'overhand grip' seems to be the common name for this technique. for lefties, you just have to be careful not to cover the ejection port when working the action. if you grip too far forward over the ejection port, you will cause yourself a malfunction.
