This element is supported in a T-shaped slot that opens laterally outward through one side of the barrel and through the breech end. The extractor engages rimless cartridges that are positioned within annular extraction grooves formed in the cartridges. A locking strap, pivotally supported on the barrel, locks the barrel in a closed position. When the strap is pivoted to a releasing position, the barrel can be tilted for loading or unloading.
