As in 1996, the Commonwealth Government, States and Territories agreed on a series of legislative changes known as the National Handgun Control Agreement (2002), resulting in the National Handgun Buyback Bill 2003, which provided Commonwealth funding for compulsory acquisition of handguns not meeting certain technical criteria. These changes were passed by State and Territory parliaments during 2003. Changes included a 10-round magazine capacity limit, a calibre limit of not more than .38 inches (9.65 mm) (since expanded under certain criteria), a barrel length limit of not less than 120 mm (4.72 inches) for semi-automatic pistols and 100 mm (3.94 inches) for revolvers, and new shooter probation and attendance requirements for handgun target shooters. Whilst handguns for sporting shooters are nominally restricted to .38 inches as a maximum calibre, it is possible to obtain an endorsement or special permit allowing the purchase and use of pistols with calibre up to .45 inches (11.43 mm) to be used for Metallic silhouette shooting or Single Action Shooting matches.
