Unless I read this incorrectly, there may be a way to 'properly register' your out-of-state unserialized handgun to make it legal in NYS (why would anyone want to do that anyways). It also appears that this does not apply to regular folk who are not gunsmiths, etc. Thoughts and apologies if this has been addressed in previous threads.
