While I do not support this bill, unless I am missing something, it doesn't apply to long guns. "Firearms" as defined in section 6102 is:
"Firearm." Any pistol or revolver with a barrel length less than 15 inches, any shotgun with a barrel length less than 18 inches or any rifle with a barrel length less than 16 inches, or any pistol, revolver, rifle or shotgun with an overall length of less than 26 inches. The barrel length of a firearm shall be determined by measuring from the muzzle of the barrel to the face of the closed action, bolt or cylinder, whichever is applicable.
As I said, I may have missed something, but this looks to me like it still only applies to what we non lawyer types would call handguns.
Never the less, this is poor legislation and should be opposed.
A healthy understanding of the way the world works.
