I think owning some weapons, for the symbolic aspect of it is part of the accomplishment of a part of your ego, a need for transition into higher spheres.

If you feel the urge or the need to satisfaction, and it is genuine, well follow it because it is true. However do not contemplate 'owning' as a finality, each experience only opens new doors in this world, it never sends you to a resting/satisfactory place until death.
