The Browning Buck Mark is a semi-automatic pistol for .22 LR cartridges, made by the Browning Arms Company. It began production in 1985 and is still being produced. The Buck Mark replaced both the Challenger and International pistol models. The same action from the pistol is used in Buck Mark rifles.
The Buck Mark pistol is designed with a straight blowback action, and is crafted using aluminum alloy. The gun uses .22 Long Rifle ammunition, with a magazine holding ten rounds. The gun comes equipped with a thumb safety as well as front and rear iron sights. Some also include a fiber-optic front sight for increased visibility. Features for some models include a bull barrel, full length scope rail, wooden comfort grips, and Pachmayr grips. It's typically issued with a ten-round magazine. There are currently (as of 2012) 15 models offered of the Browning Buck Mark pistol.
