A pistol comprising a barrel having a combustion chamber and slide translatable between an advanced configuration closing the combustion chamber, and a retracted configuration opening the chamber and in both configurations is substantially parallel to a longitudinal axis. The slide has a locking seat and longitudinal grooving. A closing organ rotatable with respect to the axis between a first and a second angular position and an element drawing in rotation the closing organ and fixed to the fore-end. The closing organ has a locking relief and a cam taking the rotation from the at least one element drawing in rotation. In the advanced configuration, the closing organ is in the first angular position so the locking relief engages the locking seat and the barrel and slide constrain each other, in the retracted configuration the closing organ is in the second angular position wherein the locking relief disengages from the locking seat and slides along the grooving so the slide can retract with respect to the barrel.

A pistol having a handle piece, a slide that is movable on the handle piece along guides, and a barrel. Provided in the handle piece is a blocking device for the forward movement of the barrel, where the blocking device has a retaining platelet that is movable in a slot and is under the action of a spring, for a barrel projection. A spring platelet is provided in the slot between the spring and the retaining platelet, where the spring platelet is designed such that it can be partially extracted from the slot transversely with respect to the center plane of the pistol. In this extracted position, the spring platelet is pivotable, together with the retaining platelet, against the force of the spring, with the result that the retaining platelet passes out of the movement path of the barrel projection and the slide can be withdrawn forward.

A firearm comprises a frame and firing control housing insert detachably mounted in the frame. A rear securement feature includes a locking slot formed in the rear wall of the insert engaging a locking protrusion formed in the rear wall of the frame which retains the rear portion of the insert in the frame. A front securement feature includes a rotatable pin inserted through holes in the insert front portion and frame. A radial retention protrusion on the pin is interposed between the insert and frame defining an interlock feature. The pin is rotatable into a first position wherein the protrusion passes through a complementary configured frame aperture allowing the pin to be removed, and a second position wherein the protrusion is not aligned with the aperture to engage the frame and prevent pin removal.

A variable barrel camming system for a firearm includes a linearly reciprocating slide supported by a frame and a barrel removably coupled to the slide for movement therewith. A cam slot on the barrel slideably engages a cam pin mounted transversely in the frame. The slot includes a cam track surface having multiple angles and contours designed to control the motion and orientation of the barrel. When the firearm is discharged, the slide and barrel initially move rearward together under recoil forces generated. The pin slides forward in the slot over the cam track surface which is configured to rotate and uncouple the barrel from the slide which continues rearward alone. The cam track surface has a varying cam profile selected to gradually dissipate the kinetic energy of the barrel/slide unit in a controlled manner, thereby reducing the felt recoil imparted to a user compared to conventional cam systems.

A firearm is disclosed which is a handgun having a frame and a slide connected to the frame which is operable to reciprocate between a forward battery position and a rearward recoil position. The barrel is connected to the frame and to the slide and it has a forward muzzle end and a rearward chamber end that rotates between a locked position and an unlocked position during cycling of the firearm. The barrel has locking elements at its forward end including a plurality of protruding lugs configured to interface with the slide in the locked position when the slide is in the battery position to prevent axial movement of the slide with respect to the barrel. Moving the trigger forward out of its released position lowers a barrel locking component out of engagement with a slidable trunnion to allow the slide and barrel to disassemble from the frame.

A pistol with a frame, including a trigger mechanism and a movable slide, in which a barrel, a recoil spring, and a firing mechanism comprising a firing pin are located. The firing pin is movably mounted in a firing pin guide, where the firing pin guide has a holding plate on the end, which is pivoted in a holding notch in the slide, the slide being affixed in one angle of rotation of the holding plate and not in one other angle of rotation, and that the holding plate has a stop retainer, which abuts against a stop level in the frame and prevents the firing pin guide (spacer sleeve) and the firing pin from moving forward with the slide when the slide is removed from the frame.
