Otherwise known as Pennsylvania State Police Application/Record of Sale. I've completed a few of these over the years and I never noted the name of the document until recently. I thought that if you buy a handgun, you complete the Form 4473, this being for anything other than private sale of longarm, and the other one I believed was national, for handguns, until I read the title. Pennsylvania is a fairly firearms friendly state for the northeast. So, it's surprising it would exist, especially since under certain circumstances in some (other) states, no paperwork is required at all, even for a handgun. 1. When did this form come about? 2. Why did it come about? 3. For what purpose did it serve? 4. I rarely purchase a handgun, let alone multiple ones, but my understanding is that if 2 it more are purchased within 5 days, yet another form must be completed. True, or not? If so, why? I particularly object (but it really doesn't matter what I think or object to) that this is a "record", as contained in the title of this form, on file with the State Police. Are these later destroyed at a later date? Presumably not.
