Ok, so I just moved officially into the state less than a year ago. I decided to sell a gun to a friend and decided to use the "proper" channel to correctly transfer the firearm to him. I used a FFL to conduct the transfer while my friend went online and filled out my info as the transferror. Well, since I never registered the firearm with maryland, a friendly Corporal gave me a ring asking me where I got the gun from and why I didn't register it with Maryland. I told him I was a transplant that just arrived. He said that I was required to register any handguns that I may have brought with me. My understanding is that this is NOT required. Is my understanding correct?
