MODERATE
The bill was updated from Session 1 to Session 2, changing the bill number and author information.

Additionally, a new section was added to protect individuals who legally owned such firearms before the law takes effect.
Scope change
The bill's scope was narrowed by adding shotguns to the list of firearms that are exempt from the prohibition on high-caliber weapons, provided they are not assault pistols or automatic firearms.
ELIGIBILITY

Added an exemption allowing possession of shotguns with a capacity to fire fifty caliber or higher ammunition if they were legally obtained before the effective date.

REQUIREMENT

Added a new section stating that the Act will not prohibit possession of eligible firearms legally obtained prior to the effective date.

Modified the definition of prohibited high-caliber firearms to explicitly include shotguns in the exemption list alongside antique pistols, revolvers, and muzzleloaders.
