Abstract
A firearm includes a frame to which a barrel and slide are slideably mounted and in which a magazine is slideably received. A bumper telescoped on a push rod slideable with the slide pushes a shell in the magazine onto a pivotal carrier. Locking wings pivotally mounted to the barrel are cammed in troughs of a cam block as the barrel and the slide slide parallel to the longitudinal axis of the barrel relative to the cam block, so that lock tabs are removably received in locking recesses in the slide to removably lock the barrel and slide together. A trigger is slideably mounted to the frame for movement parallel to the longitudinal axis of the barrel for pivoting a sear lever engagable with a biased striker and moving a safety from an interfering position relative to the striker.
Claims19
Firearm comprising, in combination:
- a frame;
- a cam block fixed to the frame;
- a barrel slidably carried in the cam block along a longitudinal axis;
- a slide slideable relative to the cam block along the longitudinal axis and capturing the barrel on the cam block, with the slide including a locking recess;
- a trigger moveably mounted to the frame;
- a striker moveably mounted relative to the frame for striking a bullet located in the barrel, with the trigger operatively connected to the striker;
- a locking wing pivotally attached to the barrel, with the locking wing including a lock tab, an outer camming surface, and an inner camming surface, with the cam block including an outer cam track and an inner cam track, with the barrel and the slide having a forward rest position relative to the cam block with the inner cam track engaging with the inner camming surface and the lock tab extending into the locking recess and with the barrel and the slide having a rearward position relative to the cam block with the outer cam track engaging with the outer camming surface and the lock tab removed from the locking recess.

Method comprising:
- providing a firearm including a barrel having a longitudinal axis and a slide slideable relative to the barrel along the longitudinal axis;
- positioning a locking tab of a locking wing carried by the barrel into a locking recess of the slide while the slide is in a forward rest position removably locking the barrel and the slide together;
- sliding the slide parallel to the longitudinal axis to the barrel out of the forward rest position;
- and
- retracting the locking tab of the locking wing from the locking recess as the slide slides out of the forward rest position.
2 more elements
Firearm comprising, in combination:
- a frame;
- a barrel carried by the frame;
- a slide slideable relative to the frame along a longitudinal axis;
- a trigger moveably mounted to the frame;
- a striker moveably mounted relative to the frame for striking a bullet located in the barrel, with the trigger operatively connected to the striker;
- a magazine slideably received in the frame, with the magazine having a top having a front and back cut in relief, with the magazine holding a shell extending parallel to the longitudinal axis against the top;
- a push rod mounted to the slide parallel to the longitudinal axis and aligned with the shell in the magazine;
- and a bumper slideably mounted to the push rod and biased toward the magazine and engaging with shell in the magazine.
5 more elements
Method comprising:
- positioning a magazine into a frame of a firearm;
- holding a shell extending along a longitudinal axis at a top of the magazine having a front and back cut in relief;
- and
- moving a bumper in a first direction along the longitudinal axis against a front of the shell to push the shell in the first direction out of the top of the magazine.
1 more element
Firearm comprising, in combination:
- a frame;
- a barrel carried by the frame;
- a striker moveably mounted relative to the frame for striking a bullet located in the barrel, with the striker moveable between a set position and a firing position, with the striker biased from the set position to the firing position;
- a trigger slideably mounted in the frame between a forward position and a rearward position, with the trigger biased from the rearward position to the forward position;
- a sear lever pivotally mounted in the frame between an engaged position and a disengaged position, with the sear lever biased to pivot from the engaged position to the disengaged position, with the sear lever in the engaged position engaging the striker and holding the striker in the set position, with the sear lever having a lobe;
- a transfer bar slideably mounted in the frame and having a forward end attached to the trigger and a rearward end;
- a linkage having a forward end pivotally connected to the rearward end of the transfer bar and a rearward end pivotally captured to the lobe of the sear lever;
- a safety slideable relative to the frame between an interfering position interfering with movement of the striker from the set position to the firing position, and a non-interfering position with the striker, with the safety engaged with and moveable by the linkage from the interfering position to the non-interfering position.
5 more elements
Method comprising:
- biasing a striker aligned with a shell in a barrel of a firearm from a set position to a firing position;
- biasing a sear lever from an engaged position to a disengaged position, with the sear lever engaging the striker in the engaged position and holding the striker in the set position, with the striker being moveable from the set position to the firing position in the disengaged position;
- and
- sliding a trigger in a longitudinal direction between a forward position and a rearward position, with sliding the trigger moving the sear lever from the engaged position to the disengaged position allowing the striker to move from the set position to the firing position.
