Back in the late 50's and early 60's at Gutersloh the Hunter and Swift drivers would have been armed with the same kit that Danny had in WW2 - 38 Smith and Wesson revolver and 12 rounds of ammo. Each year there was the ceremonial practice session conducted on the Station range. Many pranks played including hiding someone's hat behind the target, etc.
If push had ever come to shove there we only about 30 Smith and Wessons in the armoury to share among over 80 drivers. I suppose the logic was they would not all be airborne at the same time - a bit like the aircraft when you come to think of it!
