…………and that answers the question as to why Massachusetts shooters with a valid Mass license would get an out of state license from another state. I think THAT is a dangerous slope. If I were to buy an out of state pistol, with a Utah permit, and it were to be stolen and used in a crime, I could go to jail. ………..

I am confused by the two bolded sentences above.  When you say “out of state license from another state” in the first bolded, are you referring to a driver’s license or a concealed carry license/permit?  In the second bolded where you say “If I were to buy an out of state pistol, with a Utah permit” as far as I know, that is not possible.  One can buy a long gun in any other state, as long as the laws of both states are followed, but one cannot buy AND take possession of a handgun in another state.  A handgun must be shipped to a FFL holder in your home state to complete the transaction.

And in the People’s Republic of Maryland, to buy a handgun requires a HQL (handgun qualification license), along with a 16 hour training class, ‘livescan only’ fingerprints and you must get yourself to a range to fire one shot for the HQL.
