Crime boss john Gilligan is likely to survive the attempt on his life, but may have suffered permanent damage.
Gilligan was shot four times during a christening celebration at his brother’s house in Greenfort Terrace in Clondalkin.
He was taken to Blanchardstown Hospital, where his injuries were described as not life threatening.
Sources indicate that while Gilligan was responsive in the ambulance, he may have sustained lasting damage from the shots to his chest and leg.
Gilligan attempted to flee his attacker by running to the kitchen, but was shot at close range.
There were reports the 61-year-old was wearing a bulletproof vest, which may have saved his life, but this is not believed to be the case.

The crime lord was in the house prior to heading to a nearby pub for a family christening.
Gardaí believe that he may have been followed from his Jessbrook estate.
He received a wound to his leg which shattered his tibia, was shot in the chest and his hip, as well as having a bullet graze his head. An ambulance took him to James Connolly Hospital in Blanchardstown, where he is recovering today.
The crime boss was the key suspect in the slaying of Sunday Independent journalist Veronica Guerin, but he was acquitted of the murder in 2002.
In 2001 he was sentenced to 28 years in prison for drug trafficking.
Gilligan was released from prison last October, with an attempt later made on his life.
A gunman entered the Halfway House pub on the Navan Road asking for Gilligan, who was at another pub in the area.
However, Gilligan claimed that was a “Halloween prank”.
