The pistol former neighborhood watch volunteer George Zimmerman used in the fatal shooting of Trayvon Martin is going up for auction online.

In an interview with Orlando, Florida, station WOFL, Zimmerman says he had just gotten the pistol back from the U.S. Justice Department, which took it after Zimmerman was acquitted in Martin's 2012 shooting death.

Zimmerman told the station he's selling the gun because "it's time to move past the firearm."

The auction listing on GunBroker.com lists the gun as a 9 mm Kel-Tec PF-9 pistol. The auction begins Thursday at 11 a.m. EDT and the bidding starts at $5,000.

Zimmerman has said he was defending himself when he shot and killed Martin, an unarmed black 17-year-old. The shooting sparked protests and a national debate about race relations.
