摘要： A firing mechanism for a firearm includes a trigger, a forcing structure, and a spring within a cylinder, wherein while the trigger is pulled, the forcing structure moves to force the cylinder to contact a barrel and to force the spring to compress, and while the trigger is returned to an idle position, the forcing structure moves to allow the spring to decompress and to force the cylinder away from the barrel.

摘要： Provided is a trigger assembly that helps prevent malfunctioning of trigger assemblies in firearms. This is accomplished by the expedient of a convex curved projection on the upper surface of the actual trigger of the trigger assembly. Interfacing with this convex surface on the trigger is a mating concave curved projection having a surface with a radius that is similar to the radius of the trigger's concave curved projection. The trigger's concave curved projection extends relatively downwardly from the bottom side of the actual hammer of the trigger assembly. The relationship of the trigger and the hammer of the trigger assembly provides a trigger/hammer interface when the convex curved projection of the trigger is proximate the concave curved projection of the hammer. In this trigger assembly there is a captive disconnector having a disconnector engagement stabilizing projection formed as a portion of the disconnector. The stabilizing projection is generally opposite from the portion of the disconnector having a hook or small ledge where there is contact between the projecting elements of the disconnector and of the hammer. This disconnector engagement stabilizing projection limits the travel of the disconnector interfacing projection of the hammer from moving away from the disconnector engagement location of the trigger assembly.

摘要： A handgun includes a barrel which extends in a longitudinal direction, and a breechblock with a breechblock insert. The breechblock insert can be brought into a first state and into a second state where, in the longitudinal direction of the barrel, the second state has a play which is greater than a play in the first state.

摘要： A forward set trigger device for a firearm, includes a striking element that is acted upon by a main spring and has a catch interacting with a locking element, which can be disengaged from the catch by a trigger blade via a release member. The forward set trigger further includes an uncocking mechanism for the main spring by means of which a main spring support facing away from the striking element can be brought into a position that uncocks the main spring. A forward setting mechanism having a spring element, is articulated to the trigger blade and supported on a stop and which can be brought into an unstable cocked position during a forward setting movement of the trigger blade, and wherein the uncocking mechanism brings the spring element out of its unstable cocked position when the main spring support is moved into the uncocked position.

摘要： An improved firearm having a passive firing pin lock, a hammer drop mechanism, a V-block type barrel bushing, and square sight inlays is disclosed. The passive firing pin block prevents accidental discharge when the gun is dropped. The hammer drop mechanism permits the hammer to be safely lowered when a cartridge is present in the chamber without actuating the trigger. The V-block type barrel bushing accurately repositions the forward end of the barrel relative to the sights.-to provide maximum accuracy. The square sight inlays allow the user to quickly and precisely aim the firearm.
