The 68-year-old Azem Vllasi, now a lawyer, told Radio Free Europe/Radio Liberty that the assailant used a gun equipped with a silencer. He was taken to a hospital for treatment.
Police called the morning shooting in Pristina an assassination attempt, but didn't say whether they believed it was related to Vllasi's work as a communist-era leader or as a lawyer.
Police said they have arrested two suspects, and have found the pistol and the silencer believed to have been used in the attack.
President Hashim Thaci and Prime Minister Isa Mustafa denounced the shooting, wishing Vllasi a fast recovery and urged the authorities to complete the investigation.
"Such acts are unacceptable and punishable in a society where the main priority is the strengthening of the rule of law and order," Thaci said.
The government issued a statement saying that it "considers that such acts are totally unacceptable in a democratic society".
