How would this work for 3 or 4 generation private gun sales? How would this work on 3d printed guns, etc? This works for just the comically retarded gun owners. This also wont work in states where credit unions wont cuck out to the liberal insanity. what if i bought the gun on private with cash? Sure if you have Chase, maybe they'll enforce this, but in this day and age, this will just fail, and there's just way too many variable for this to be enforced properly. As an example, most gun sales in the midwest are NOT bought at the gun store
