the only difference is this...
It is now full fledged Registration.
When you purchase a pistol you still MUST register it.
The only difference is how you do it. If you have no problem running down to the police station (for me that was the easiest), you can still do that.
If you want clarification on the rest of the other ways you can register via snail mail, i can post that also.
Pistol Inspection was Registration. They renamed it to registration and you do not have to take the pistol with you to the police station.
