ABSTRACT:
A double barrel derringer has an extractor mechanism which includes a T-shaped extractor element supported in a T-shaped slot which opens laterally outwardly through one side of the barrel and through the breech end thereof and communicates with the cartridge chambers. The extractor engages rimless cartridges disposed with the cartridge chambers within annular extraction grooves formed in the cartridges. A locking strap pivotally supported on the barrel locks the barrel in a closed position. Pivotal movement of the strap to a releasing position allows the barrel to be tilted from its closed position to a loading/unloading position. Further pivotal movement of the locking strap operates the extractor to simultaneouslly partially extract both cartridges from the cartridge chambers. The extractor is arranged for general lateral movement relative to the barrel to release the partially extracted cartridges which may then be dumped or manually removed from the cartridge chambers. A spring arranged between the locking strap and a groove in the extractor biases the extractor towards the cartridge.
