This class is available to target shooters and certain security guards where your job requires possession of a firearm. To be eligible for a Category H firearm, a target shooter
Target shooters are limited to handguns of .38 or 9mm calibre or less and magazines may hold a maximum of 10 rounds. Participants in certain "approved" pistol competitions may acquire handguns up to .45", currently Single Action Shooting and Metallic Silhouette. IPSC shooting is approved for 9mm/.38/.357 sig, handguns that meet the IPSC rules, but larger calibres are not approved for IPSC handgun shooting contests in Australia.[3] Category H barrels must be at least 100mm (3.94") long for revolvers, and 120mm (4.72") for semi-automatic pistols unless the pistols are clearly ISSF target pistols: magazines are restricted to 10 rounds. Handguns held as part of a collection were exempted from these limits.
