You thought just because SB1160 was already signed into law as Public Act 13-3 that they were done with it?
According to the bill listing for Raised Bill SB1094 on the Connecticut General Assembly website there are two brand new amendments that actually modify SB1160/Public Act 13-3.
Senate LCO Amendment #8513 [pdf]
Senate LCO Amendment #7936 [pdf]
It looks to me they are trying to correct some of the mistakes they made. On a quick skim of the amendments I see clarification about banned items purchased but not delivered prior to the new law, what appears to be an exemption for high-end rimfire target pistols, and what seemed to be clarification that the new law does not apply to firearms purchased with a Federally-issued firearms collector’s license (C&R/FFL03) There also seems to be clarifications on exemptions for law enforcement and state agencies.
