A rocket motor ignitor assembly that may be used in a shoulder-fired rocket system. The rocket motor ignitor assembly may include a delay ignitor operable to ignite a rocket motor propellant, a stab firing pin operable to activate the delay ignitor by contacting the delay ignitor, and a biasing element coupled with the stab firing pin. The stab firing pin may have a length to diameter ratio greater than two, as well as relief grooves allowing air to vent past the stab firing pin as it travels toward the delay ignitor to activate it. The rocket motor ignitor assembly may also include a guide stop to limit penetration of the stab firing pin into the delay ignitor.

The invention disclosed herein provides a system and a method for a single-use firearm and personal defense system. The system includes a single-use firearm capable of firing a projectile. The single-use firearm capable of firing a projectile comprises a firearm frame, at least a first barrel, a trigger operable to actuate a striking of at least a first ammunition cartridge, and an ammunition locking system, wherein the ammunition locking system permanently locks the at least first ammunition cartridge within the firearm, whereby once locked, the at least a first ammunition cartridge may not be removed or reloaded without permanently damaging the firearm. The system also incorporates internal electronics for, among other things, tracking, notifying, and monitoring the firearm and its users.

Adjustability of trigger pull force is enable by the use of a spring interfacing with a trigger shoe counterweight. The spring force is adjustable by use of a set screw interfacing with the spring. A pivot arm member acts between a trigger shoe counterweight and a firing pin release arm to fix the ratio of trigger shoe pull force and firing pin release arm force.

Trigger-cycled firearms have a frame, a barrel, a bolt assembly connected to the frame in registration with the barrel and operable to reciprocate between a retracted position and a forward battery position, a trigger lever connected to the frame and operable to move between a forward rest position and a rearward actuated position, and the trigger lever operably connected to the bolt to move the bolt from the forward battery position to the retracted position and to release the bolt to the forward battery position and discharge the firearm in response to movement of the trigger lever from the forward rest position to the rearward actuated position when the bolt is in the forward position. There may be a connector bar pivotally connected to the frame and operably engaged to the bolt assembly and to the trigger lever. The connector bar may be slidably connected to the bolt assembly.

A toolless slide backplate for a firearm that comprises an extractor lock and a striker assembly lock. The extractor lock is dimensioned to cover and contact an extractor plunger when installed, and is held in place via an interplay with the extractor plunger. The striker assembly lock is dimensioned to cover the striker components when installed. The striker assembly lock covers the trigger connector of the frame of the firearm such that a disassembly opening is not required.
