Hey, I represent that remark.
My big pet peeve right now is on that I've been guilty of in the past: "Go rent a bunch of guns until you find one you like." The problem with this advice is that newbies don't have objective criteria on what makes a gun good, so you'll end up with someone at the rental counter trying out every 9mm in the case and then eventually settling on the Taurus PT24/7 POS because "the grip felt really nice."
