How many large capacity magazines are there in Connecticut?
We were unable to find this number, but the NSSF estimates that it could be in the tens of millions. NSSF used the following methodology to arrive at this figure.
Based on Connecticut's percentage of National Instant Criminal Background Check System checks in the Unites States, NSSF estimated that the number of firearms owned by Connecticut residents is about three million. About one million of these firearms are handguns, of which 21%, or 231,000 use large capacity magazines. About 1.2 million are rifles, of which 30%, or 372,000 use large capacity magazines. Assuming four magazines owned for every firearm (assuming every firearm comes standard with at least two magazines), NSSF asserts there are over 2.4 million large capacity magazines in Connecticut that originated at the retail level. The NSSF final figure is larger than this because it counts firearms already in the state and those not purchased at the retail level.

More than 50,000 so-called ‘assault weapons’ were registered in Connecticut by the December 31st deadline under the new gun law.
However, apparently hundreds more people attempted to file at the last minute, but got stopped by the post office.
News 8 reported to you several times about the long lines of gun owners at the end of last year, lining up to comply with the state’s new gun registration requirements passed in the aftermath of the tragedy at Sandy Hook.
While final official numbers are not expected for a few more weeks, the State Police report that as of today, a total of just over 50,000 so-called assault weapons have been registered and 38,000 high capacity ammunition magazines.
Apparently there were several hundred more Connecticut residents that attempted to file the proper applications, but missed the deadline because the post office closed early on New Year’s Eve and their applications were postmarked in January.
