Depends on the gun and magazine. You can get 33 rounders for 9mm Glocks, for example, and a standard capacity magazine for an AR-15 is 30 rounds. Magazines with more than a 10 round capacity are illegal in Connecticut unless you owned them prior to 2013 and registered them with the state, though, and you can’t carry them loaded with more than 10 rounds even if you do legally own them. So either multiple guns, multiple magazines, or illegal magazines.
