Connecticut's permits are recognized by 21 states across the US. The map below shows which states honor the concealed carry permit of Connecticut.
Connecticut does not honor any other state's permits.
In Connecticut, it is prohibited for someone to keep a loaded firearm in their vehicle without a concealed carry permit if it hasn't been issued yet. However, you can keep an unloaded BB gun in your vehicle's trunk or in a locked container other than the glove compartment. This law does not apply to the interstate transportation of the firearms as long as the firearm is unloaded and is locked away in a safe compartment/storage box.
It is also prohibited in Connecticut to possess or carry any shotgun, rifle, or muzzleloader of any gauge or caliber while such long gun is loaded.
