PC Jack Ginger, PC Jessica Hamblett and PC Richard Hayes were on patrol when they heard a loud bang coming from just metres away, which they believed to be a firearm discharging.
The suspect was spotted fleeing the scene, carrying a black bin liner.
The officers pursued him and, after a failed attempt to escape in a vehicle which had driven on to the pavement to avoid the officers, they successfully arrested him at the scene.
A search of the area resulted in the discovery of a black bin bag, containing a converted firearm and an empty cartridge.
The offender was subsequently sentenced to five years imprisonment.
GMP Chief Constable Stephen Watson said: “Our three officers showed amazing courage and tenacity in the way they responded to an incident which was violent, dangerous and unfolded in a matter of seconds.
“Thanks to their actions a violent man was removed from our streets and prevented from causing further harm.
“My congratulations go out to PC Ginger, PC Hamblett and PC Hayes, who without a doubt represent the finest of police officers.
"They deserve every bit of recognition they receive, and I am extremely proud that they wear the GMP uniform.”
