Sure. But about half the time I buy through a FFL I get a delay and have yet to get a call-back. First, middle and last names are as common as they can be. And it seems that lots of dealers are spooked enough about the delay they won't fall back on the 3-day rule. So, if I find it person-to-person I jump on it.
I kind of have the same problem. I usually get delayed a day or 2, sometimes no call back. Filling out a 4473 doesnt bother me but it sucks at gun shows when the dealer is from out of town or I am at a show like wanenmacher's and get delayed.
