welcome to OC forum, and forgive the distant comment from a non-attorney,
but NH statutes state, IAW 159.6 if you are issued a permit, then you are authorized without reservation to carry. http://www.gencourt.state.nh.us/rsa/html/xii/159/159-mrg.htm
however, i am more concerned you might wish to change your post as to where you, as an admitted minor, got your firearm...as NH statute 159.12 specifically state:
I. Any person who shall sell, barter, hire, lend or give
to any minor any pistol or revolver shall be guilty of a misdemeanor.
II. This section shall not
(a) Fathers, mothers
, grandparents, guardians, administrators or executors who give a revolver to their children or wards or to heirs to an estate.
therefore, your 'gift' from someone other than your caregivers could lead to a conflict if someone in authority challenges you while carrying. especially if the authorities question your caregivers about where and how you obtained the firearm.
you did not mention when you might reach your majority. but this coupled w/the acknowledged conflict on your carrying the firearm between your caregivers, should give you second thoughts that while able to carry, i'm not sure the parental 'discussions' and family strife warrant the overall fire fights that might ensue.
you also did not mention if you have participated in any formal firearm training program which also might go a long way to ease the parental concern if you show you have received appropriate guidance.
Just an observation from afar to ease your way along your long journey dealing with firearms.
