I'm perfectly ok with registration, theoretically. I'm also perfectly ok with Obamacare, socialism, and Communism, theoretically. Theoretically, a registration system might make a difference in solving one crime out of a thousand. Theoretically, it would allow a gun manufacturer to track down the second, third, or fourth owner of a firearm in the event of a factory recall. Theoretically, in a socialist system, everyone lives in a land of plenty where no one wants for lack of food, housing, medical care, or employment. But as one of the wise members of this forum says in his signature line, "The difference between theory and reality is that, in theory, there is no difference between theory and reality."
Practically speaking, gun registration lists do not make any difference in catching criminals. They don't allow gun manufacturers to track down owners of recalled firearms, because we as gun owners demand that they be kept at least somewhat confidential. There's a damn good reason for that, as Florida found out with their CCW system. (Once again, theory and reality diverge at an exponential rate!) Finally, every single registration list has been used at some point to allow the confiscation of privately held firearms. The old standbys are the Soviet Union and Nazi Germany, but it's happened in Australia, the UK, Canada, and apparently in some cases here in Hawaii. Registration is the cornerstone of confiscation, and I will never be ok with registration, permits to acquire, or any of the other trappings of totalitarianism the state of Hawaii has saddled the citizenry with.
