In one year I would expect to see minimal change, so you'd better revamp it to restrict more potential buyers. In another year when the projected results aren't achieved you'd probably have to tweak it again to limit the types of guns that are available for purchase. That didn't work? Those semi-auto rifles and shotguns must be the culprit. That didn't work either? Well, it would be too politically damaging to revert to the way it was, so let's just move the goalposts to make it look like we accomplished something.
