Hi Evon and welcome to the Buds community. You would need a semi-auto shotgun with a standard tubular magazine and not a CT restricted detachable box magazine. Several options are available: budsgunshop.com/product_info.php/products_id/160754/military+armament+mac+1014+12ga+18.5+barrel+wood+stock+5+1 ------------------------------------------------------------------ budsgunshop.com/product_info.php/products_id/411561248/panzer+arms+m4+12ga+18.5+disruptive+grey+cerakote+walnut+stock+ambidextrous+5+1 --------------------------------------------------------------------- budsgunshop.com/product_info.php/products_id/172180/601+sa+sport+12+ga-3+black+20+synthetic+mc-3 --------------------------------------------------------------------- budsgunshop.com/product_info.php/products_id/160749/mac+2+tac+12+18.5+ni+sy+3 ----------------------------------------------------------------------- Cheers, stay safe and enjoy!

Here are a couple to look at: budsgunshop.com/product_info.php/products_id/160754/military+armament+mac+1014+12ga+18.5+barrel+wood+stock+5+1 />budsgunshop.com/product_info.php/products_id/172180/601+sa+sport+12+ga-3+black+20+synthetic+mc-3 />

Good evening to you!! Sorry but magazine feed semi auto shotguns are not compliant in Connecticut. You would need either a standard cylinder magazine semi auto or a pump to be compliant in your state. See below for a few options. Hope this helps. Have a good rest of your day.

Hi Evon, A semiautomatic shotgun that has the ability to accept a detachable magazine is prohibited in CT.
budsgunshop.com/feeds/state_reg/connecticut_restrictions.pdf ,
A CT legal semi-auto shotgun is the Military Armament MAC 1014, a clone of the Benelli M4 tactical shotgun, but in walnut trim budsgunshop.com/product_info.php/products_id/160754/military+armament+mac+1014+12ga+18.5+barrel+wood+stock+5+1 ,
Stay safe & have a great day!

I think a pump action would be the way to go.
