An action for a firearm uses a rotating barrel on which are mounted lugs and a cam follower. The barrel is positioned coaxially within a tube fixed to the frame of the firearm. A cam, engaged by the cam follower, is also fixed to the frame. A gas space is defined between the tube and the barrel by a thrust surface on the barrel and a reaction surface on the tube. A gas port connects the gas space with the barrel's bore. A slide overlies the tube and defines longitudinally oriented grooves which receive the lugs when the barrel is rotated by interaction between the cam and the cam follower to align the lugs and the grooves. Motion of the barrel is arrested by interaction between the cam and cam follower, and motion of the slide relative to the barrel is permitted when the lugs align and engage the grooves.

Fire control mechanisms for a firearm include a trigger disconnect assembly and an action lock mechanism which work together to ensure safe and reliable firearm operation. The trigger disconnect uses a spring biased disconnector pivotably mounted on the trigger to actuate the sear and release a hammer sear upon firing. The hammer sear engages a compliant interface formed by a spring which actuates the action lock to unlock the bolt after the trigger has been pulled.
A firearm using blowback action has a barrel which is movably mounted within a shroud which is fixedly mounted on the firearm's frame. A gas space is formed between the barrel and the shroud by a difference between the inner diameter of the shroud and the outer diameter of the barrel. At least one gas port provides fluid communication between the bore of the barrel and the gas space. During firing of a cartridge, pressurized gas in the gas space applies a force to the barrel which moves relatively to the shroud away from the muzzle end of the firearm to engage a slide or bolt, helping to move it out of battery and extract the spent cartridge casing. Gas is vented to the atmosphere through a gas vent defined between the barrel and the shroud in fluid communication with the gas space.

An inertial decoupler and suppressor assembly, associated components, and associated methods. The inertial decoupler is adjustable to change a preload of a spring biasing a piston toward an at-rest position and/or to change a permitted travel distance of the piston away from the at-rest position. The inertial decoupler can be removable from the suppressor and usable with other suppressors, or can be integrated with a dedicated suppressor.
A sear mechanism for a firearm pivotably mounts a sear body on a sear lever which is pivotably mounted on the firearm frame. An actuator lever is also pivotably mounted on the frame. The actuator lever is pivoted by a trigger bar connected to the firearm's trigger. Pivoting of the actuator lever when the trigger is pulled allows the sear lever to pivot. Pivoting of the sear lever allows the sear body to fall off of a surface on a striker, releasing the striker to discharge the firearm.
An ammunition magazine for a firearm uses a spacer to extend the grip. The spacer is attached to the magazine's tube using a combined fastener and detent mechanism which acts between the magazine's butt plate and floor plate. The butt plate is attached to the magazine tube and the spacer is captured between the butt plate and floor plate.
A magazine for feeding ammunition to a firearm includes a tube surrounding a longitudinal axis and defining a central space for receiving the ammunition. The tube has first and second ends. A follower is slidably movable within the tube. A butt plate is removeably attached to the first end. The butt plate defines a bore. A plunger is movably positioned within the bore and includes a first mounting cam. A first catch, mounted on the butt plate, is engageable with the tube proximate to the first end. The first catch is movable relative to the butt plate in a direction transverse to the longitudinal axis. The first catch includes a cam follower engageable with the first cam. A spring acts between the plunger and the follower for biasing the plunger toward the butt plate and the follower toward the second end.
