If your coming from state side,i`m not to sure what permits or licenses Guam honors.But if you are from Guam and are licensed,you have the right to carry shotguns,rifles,or handguns in a non concealed status.While carrying in Guam in public weapon must be in a holster and exposed,weapon maybe loaded but chamber must be empty.While in a vehicle
weapon must be unloaded and magazine must be kept in a secure place(locked glove box trunk etc).Prohibited from a thousand feet from any k-12 school,not illegal to carry in establishment that serve alcohol,but thats not advisable unless your concealing.And basically your at the mercy of establishments that may prohibit you to enter there establishments.Hope this helps answers your question.
You wouldnt be able to get one because your not a resident,i talked to the local AG`S office and they said Guam issues to residents only.
Yes, only one left would be how do I get licensed as a nonresident!
