Patent number: 11965705Abstract: 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.Type: GrantFiled: September 27, 2021Date of Patent: April 23, 2024Assignee: SMITH & WESSON INC.Inventor: Simon M. Muska

Publication number: 20230243609Abstract: An arrangement of a hammer and a sear for a firearm having a frame is disclosed. The arrangement includes a hammer mountable within said frame for pivoting motion about a hammer pivot axis. The hammer includes a hammer body defining a hammer lug surrounding said hammer pivot axis and a hammer face positioned distal to said hammer pivot axis. A slot is positioned within said hammer body. A catch surface is positioned on said hammer body within said slot. A sear is mountable within said frame for pivoting motion about a sear pivot axis. The sear includes a sear body defining a sear lug surrounding said sear pivot axis and an action surface positioned on said sear body distal to said sear pivot axis. The action surface is movable into and out of engagement with said catch surface upon rotation of said sear body about said sear pivot axis. At least a portion of said sear body is received within said slot.Type: ApplicationFiled: February 1, 2023Publication date: August 3, 2023Inventor: Simon M. Muska

Publication number: 20230235982Abstract: A trigger return and safety mechanism are mountable on a frame of a firearm. The trigger is mountable on the frame and pivotable about a trigger pivot axis. A strut is pivotably attached to the trigger at a strut pivot axis oriented parallel to and offset from the trigger pivot axis. The strut comprises a spring bearing surface and a safety bearing surface. A spring acts between the spring bearing surface and the frame for biasing the trigger into a reset position after the trigger has been pulled. A body is mountable on the frame, the body being movable between a first position wherein the body is not engageable with the safety bearing surface, thereby allowing pivoting motion of the trigger, and a second position wherein the body is engageable with the safety bearing surface thereby limiting pivoting motion of the trigger.Type: ApplicationFiled: January 26, 2023Publication date: July 27, 2023Inventor: Simon M. Muska

Patent number: 11703292Abstract: A bullpup shotgun which ejects shells from the bottom of its action has a reciprocable cover which, when in a closed position, overlies the breech end of the shotgun's barrel. When in an open position, the cover is in spaced relation to the barrel breech end, allowing access to the shotgun's action to clear an ammunition feed malfunction. The cover is mounted on a butt stock, and is slidable or rotatable relatively to the shotgun's butt stock to effect motion of the cover between the open and closed positions.Type: GrantFiled: April 5, 2022Date of Patent: July 18, 2023Assignee: Smith & Wesson Inc.Inventor: Simon M. Muska

Publication number: 20220228825Abstract: A bullpup shotgun which ejects shells from the bottom of its action has a reciprocable cover which, when in a closed position, overlies the breech end of the shotgun's barrel. When in an open position, the cover is in spaced relation to the barrel breech end, allowing access to the shotgun's action to clear an ammunition feed malfunction. The cover is mounted on a butt stock, and is slidable or rotatable relatively to the shotgun's butt stock to effect motion of the cover between the open and closed positions.Type: ApplicationFiled: April 5, 2022Publication date: July 21, 2022Inventor: Simon M. Muska

Patent number: 11326845Abstract: A bullpup shotgun which ejects shells from the bottom of its action has a reciprocable cover which, when in a closed position, overlies the breech end of the shotgun's barrel. When in an open position, the cover is in spaced relation to the barrel breech end, allowing access to the shotgun's action to clear an ammunition feed malfunction. The cover is mounted on a butt stock, and the butt stock may be movable relatively to the shotgun's receiver to effect motion of the cover between the open and closed positions.Type: GrantFiled: July 9, 2020Date of Patent: May 10, 2022Assignee: Smith & Wesson Inc.Inventor: Simon M. Muska

Patent number: 11306995Abstract: A shotgun is formed of sub-assemblies which include a lower receiver upon which a butt stock and an upper receiver are mounted. The lower receiver houses the fire control mechanism, the butt stock includes an ammunition elevator and a breech cover. Magazine tubes, ammunition cut-offs, a selector, a selector interrupter and the barrel are mounted on the upper receiver.Type: GrantFiled: July 9, 2020Date of Patent: April 19, 2022Assignee: Smith & Wesson Inc.Inventor: Simon M.

Patent number: 11035636Abstract: A shotgun has right and left magazines from which ammunition may be fed to the action using a selector mounted on a movable fore-end chassis whose motion cycles the action. An interrupter prevents the selector from switching between magazines unless the action is in battery with the fore-end chassis fully forward toward the muzzle end of the shotgun. Respective right and left outer cut-offs on the magazines cooperate with an inner cut-off to ensure proper coordination of ammunition feed as the action is cycled by motion of the fore-end chassis. The outer cut-offs are also manually operable to permit removal of ammunition from the magazines without cycling the action.Type: GrantFiled: July 9, 2020Date of Patent: June 15, 2021Assignee: Smith & Wesson Inc.Inventor: Simon M. Muska

Patent number: 11022386Abstract: A breech cover interlock coordinates the motion of a breech cover with the motion of the fore end of a pump action firearm. The interlock features an action bar which is connected to the fore end and has a catch which is engaged by a latch mounted with the cover on a movable buttstock. Engagement between the catch and the latch prevents the buttstock and cover from moving and thereby exposing the firearm's breech while the firearm's action is in battery as evidenced by the position of the fore end. Motion of the fore end out of battery disengages the latch and catch and permits the cover to be moved out of overlying position with the breech to permit access to the breech to clear a malfunction.Type: GrantFiled: August 14, 2020Date of Patent: June 1, 2021Assignee: Smith & Wesson Inc.Inventor: Simon M. Muska
