John gave Tony a 12 bore Mossberg 500 to replace the Browning Over/under he was originally carrying. This was the gun Tony came close to using during the encounter at RAF Lossiemouth.
The Mossberg 500 is a magazine fed, pump action shotgun available in many different hunting and police models. Stocks are made of polymer or wood. It is a strong, reliable shotgun which is often chosen by military and police units or civilians as a slightly cheaper alternative to the Remington 870.
