There is a de facto registry of the sale (including the serial numbers) of handguns and long guns purchased in the state that is maintained by the Department of Emergency Services and Public Protection (DESPP).By law, Connecticut is a May-Issue state based on an applicant's suitability to be granted a pistol permit, but court precedence has established that issuing authorities must grant permits on a Shall-Issue basis for the vast majority of applicants who meet the state's statutory qualifications.Additionally, unlike other May-Issue states, Connecticut law does not require the applicant to provide a "necessary and proper reason" (or in other words, show "good cause") for needing a pistol permit.It is typically much more difficult to obtain temporary pistol permits in larger cities, such as Bridgeport, Hartford, and New Haven.The proposal also called for background checks for private gun sales and a new registry for existing magazines that carry more than 10 bullets.The law makes Connecticut the first state to establish a registry for people convicted of crimes involving dangerous weapons.It also requires background checks for all gun sales, restricts semiautomatic rifles, and limits the capacity of ammunition magazines.Connecticut has bans on defined 'assault weapons', which includes selective fire firearms unless purchased before October 1, 1993, and a limited list of semiautomatic AR, AK, and SKS variants.Machine guns that can only fire fully automatic are legal in Connecticut if they were possessed prior to April 4, 2013, and registered on or before January 1, 2014.Connecticut statutes allows police, after investigating and determining probable cause, to get a court warrant and seize guns from anyone posing an imminent risk of harming themselves or someone else.The judge (1) must, when assessing probable cause, consider recent acts of violence, threatening, or animal cruelty and (2) may, when assessing imminent risk, consider such factors as reckless gun use or display, violent threats, alcohol abuse, illegal drug use, and prior involuntary psychiatric confinement.[18][19] As of October 1, 2019, all manufactured guns will be required to have a serial number obtained from the Department of Emergency Services and Public Protection engraved.[21] State laws do not explicitly preempt local ordinances, but courts have found intent of preemption in regards to firearm sales, hunting and carrying (openly or concealed) with a state-issued permit.
