Hi Benjamin and welcome. Unfortunately, no, it is not CT legal due to "pistol grip", "magazine attachment outside of pistol grip", "threaded barrel". Details under "Handguns" here: budsgunshop.com/feeds/state_reg/connecticut_restrictions.pdf -------- cheers and stay safe!

The Rossi RS22P 22LR with a 6-inch barrel (often referred to as the Rossi Brawler) is CT legal as a single-shot, non-semiautomatic pistol.
