Handgun Metallic Silhouette is a rimfire and centrefire revolver and pistol shooting discipline where competitors aim to knock down metal animal-shaped targets. The targets are placed on steel stands in banks of five and set at a variety of known distances, with the competitors having a certain amount of time to knock as many down as they can. The firearms used must fall into one of four categories: Production, Revolver, Standing and Unlimited, and there are three official matches: Big Bore, Smallbore and Field Pistol, with each match having its own categories.
