Over-and-under shotgun apparatus and method
First Claim
1. An over-and-under shotgun apparatus, comprising:
- a firearm comprising a barrel and a receiver;
a curved abutment interface formed between the barrel and the receiver, the curved abutment interface comprising a convex portion and a concave portion, the convex portion exerting a bearing force against the concave portion;
a pressure adjustor coupled to one of the shotgun barrel or the receiver to adjust the bearing force.

Abstract
An over-and-under shotgun apparatus includes a radius track which serves as a hinge for articulating the barrel portion of the shotgun apparatus relative to the receiver/stock portion of the shotgun apparatus. The radius track is defined by a female or concave portion formed on the monoblock attached to the shotgun barrels, and a male or convex portion formed on the frame or receiver section. The radius track defines a pivot axis that is spaced from the radius track. The radius track provides a substantial surface area sufficient to absorb all of the recoil force generated when the shotgun is discharged. No additional abutment surfaces are needed. A further aspect of the invention involves a novel trigger assembly, including a striker which moves toward the front end of the firearm when the firearm is cocked, and moves toward the butt end of the firearm when the trigger is pulled to discharge the firearm. Yet another novel aspect of the invention relates to a four-position safety switch for selecting the firing sequence of the upper and lower barrels.

15. An over-and-under shotgun apparatus, comprising:
-
a proximal end comprising a receiver and a stock;
a distal end comprising at least one firearm barrel;
a hinge formed between the proximal end and the distal end, the hinge allowing the proximal to pivot relative to the distal end about a pivot axis, the hinge comprising a radius track between the proximal end and the distal end, the radius track providing a sliding engagement interface between the distal end and the proximal end;
a force applicator operatively coupled to the sliding engagement surface to apply a friction force on the sliding engagement surface. - View Dependent Claims (16, 17, 18, 19)

20. A firearm apparatus, comprising:
-
a receiver/stock portion;
a barrel portion comprising at least one barrel;
a trigger assembly comprising a striker, a firing pin, and a striker bias member operatively coupled to the striker to exert a bias force on the striker, the striker being moved toward the fore end of the firearm to overcome the bias force of the striker bias member when cocking the firearm, the striker providing an impact force toward the aft end of the firearm upon discharge of the firearm to actuate the firing pin. - View Dependent Claims (21, 22, 23, 24)

25. A method of discharging a firearm, comprising:
-
providing a firearm comprising a distal end having a barrel and a proximal end having a stock and a receiver;
providing a trigger assembly comprising a trigger, a firing pin, and a spring bias;
cocking the trigger to overcome the spring bias, the spring bias providing a compressive force toward the butt end of the firearm;
actuating the trigger to release the spring bias and produce a compressive, rearwardly directed force toward the butt end of the firearm;
redirecting the compressive force toward the muzzle end of the firearm and causing the firing pin to move forward toward the muzzle end of the firearm to discharge the firearm. - View Dependent Claims (26)
