What were you doing when you were being shot at? What venue were you in?
The only guns we have at the moment are equipped on the rovers and the rovers only have them equipped if you are in a venue that has vehiclular combat, like Score It, Keep It, or Get It. If you joined one of those venues, you would have also had a gun at your disposal. If you were just flying over the venue in a bubblecraft or running through with an avatar, however... yeah... you would have just been a moving target.

Edit: Centronias beat me to the punch.
