The way I carry the point of the extension protrudes a bit - but it isn't enough to be a problem. Though I have considered modifying mine like several others have done to remove the point and maybe shorten it just a tad.At the angle I carry the rear of the grip protrudes more.
Kind of depends on the person, clothing, and forward cant. I carry around 2:45 myself but since I like a strong forward cant the extension sticks out more than the rest of the grip and it does print a bit sometimes. But like I've said before, it isn't enough to keep me from using the extension, but some day I may take and grind it down some since I don't really need all of the length or the lip.At 2:30-2:45 they do not print.
