Props: What We Need And Why We Need Them?

Our group needs to get 5 guns for the scene. We need to get 4 police issue rifles for the police officers, this will help add to the identification of the character for the audience so that the audience will easily be able to tell that they are police men, however, we need to set the scene in England so, there will be no pistols and only the police issue rifles. The girl will have a shotgun as they are common place in England, either this or a hunting rifle, as many people in the UK go hunting.
