A pistol comprises a barrel connected to a frame that has a grip portion defining an elongated magazine well. A magazine defining a plurality of chambers is removably receivable within the well. A trigger assembly connected to the frame engages a magazine with a follower or cam surface by which trigger assembly advances the magazine within the well and indexes the magazine along its length to sequentially align each chamber with the barrel, and sequentially discharge each cartridge in the magazine. The follower elements may be arranged parallel to the length of the magazine so that each may be associated with a particular chamber. A “safety” condition is effectible by pushing a loaded magazine downward and into a concealable condition with its chambers out of alignment with the gun barrel and wherein a transfer bar safety blocks the hammer from inserting its firing pin into a magazine chamber.

A mount for mounting a firearm sound suppressor or silencer to a firearm muzzle or muzzle device operates by using primary mounting lugs on the suppressor which engage sockets on the muzzle device. The primary lugs prevent the suppressor from axially moving with respect to the muzzle device, thus causing them to be fixed together as a unitary device. Angled bearing faces on the muzzle device and the sound suppressor are pressed against each other by rotating the sound suppressor on threads which drive the angled bearing faces together, thus tightening the primary lugs within their sockets. Backup lugs on the silencer engage an annular groove on the muzzle device to retain the silencer on the firearm to which it is mounted in case of failure of the primary lugs. Rapid attachment and detachment are supported by these structures.

A linear encoder may be used to accurately determine a number of cartridges within a magazine. Further, using a set of magnetic sensors within a buffer tube of a firearm, it is possible to determine whether a cartridge is loaded within a chamber of the weapon and/or whether the firearm is jammed. The determination of cartridges within the magazine in conjunction with the determination of whether a cartridge is in a chamber of a firearm can give a user an accurate ammunition count. Further, the use of the linear encoder makes it possible to accurately determine the cartridge count when different cartridges are loaded into the magazine or when the magazine degrades in quality over time. Moreover, the ability for magazines to communicate with a firearm enables a user to determine a total available ammunition to the user in a single display without individually checking each magazine.

A new kind of active protection system (APS) called SNAP (scalable networked active protection) will be a light and affordable means of protecting vehicles and infrastructure against rockets and missiles. The APS system is built from modules, each of which is itself a stand-alone APS. Since each unit is a stand-alone APS, the only single points of failure are the User Interface (UI) in the vehicle cab and the Data/Power Router (DPR). SNAP instead takes advantage of each module protecting a relatively small area to employ vastly lower cost components. In addition, each SNAP module is disposable in that when its countermunition is initiated, the entire module is consumed and subsequently replaced in the field. This approach allows the system to be very compact and lightweight.
