To get your license to carry a Firearm, you first have to take a firearm safety course before you can apply. To get your License you have to take the certificates you recieve from the class to your local police department where they will conduct a criminal back ground check on the applicant. If the applicant does not have a criminal Conviction or a Mental Illness then they should not have an issue getting their License to carry in Massachusetts, Connecticut or any other states. Hope this cleared up some questions. You can also visit our website at www.ssdtacticaltraining.com.
