The latest botched gangland hit at a north Dublin Lidl store failed because the gun the shooter was using jammed.
The Irish Mirror can reveal that the gun misfired and gun man could only fire one round before having to flee the scene.
The hit was against convicted armed robber Noel Boylan who was shot outside the supermarket in a gangland hit.
A source said: "This shooting was an attempt to murder this man but the gun jammed as the shooter launched his attack.
"The criminals are storing their guns in fields and derelict buildings - they are normally wrapped in plastic and cloth and can be rubbed with grease or oil.
"The thing is these guns are high precision weapons and they need to be carefully maintained - the criminals are not maintaining them."
Noel Boylan's son Lee Boylan was riddled with bullets in a botched hit earlier this year - on that occasion the gunman used a small .22 calibre handgun that fired underpowered rounds.
He is still suffering from his injuries and is understood to be making a slow recovery.
A number of botched hits have taken place in which a gun has jammed or misfired.
In one famous incident a gun used by criminals who were en route to kill Michael Frazer, used a gun with the wrong-sized ammunition.
Gardai have renewed their appeal for help in tracking down the shooter at the shopping centre at Blakestown Way, Dublin.
The gardai in Blanchardstown have requested that people who witnessed anything in the "Blakestown Way, Blanchardstown area at approximately 5.20pm on Saturday the 1st June 2019" to make contact.
