Police believe drugs and greed likely fuelled the targeted attack on a 31-year-old in Sydney's southwest on Sunday.
The gunman fled the scene on St Johns Rd in a white Audi and remains on the run.
The Audi was found set alight a short time later in the neighbouring suburb of Wakeley.

A grey Jeep believed to have also been involved in the shooting has been seized at Bossley Park, where a 33-year-old man was arrested on Monday morning.
The man was later charged with accessory to murder and not disclosing the identity of the passenger or driver as required.
He was refused bail and is set to appear in Parramatta local court on Tuesday.
The murdered man allegedly had links to organised crime syndicates involved in the illicit drug market, police say.

Detective Superintendent Daniel Doherty said involvement in organised crime in pursuit of "the high life" often ended the same way.
"It just comes down to what we always talk about, and it's drugs and greed.
"There's consequences if you're going to be involved in organised crime networks and we see it over and over again, they end up dead on the street," he told reporters on Monday.
As well as investigating the shooting, police are focusing on preventing retaliatory attacks. (HANDOUT/ABC NEWS)
Relatives left behind are grieving the sad and tragic death of a man shot multiple times outside the family home, he added.
"It's a very sad, tragic situation, despite what his history may have been, or what his links are ... it's terrible for his family," Det Supt Doherty said.
Significant police resources are being directed to the investigation of the brazen daylight shooting in the middle of the festive season as well as focusing on preventing any further attacks in retaliation.
