Slide Divot Striker Lock for Trigger-Free Firearm Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms require trigger actuation for disassembly, which can lead to unintended discharge if live ammunition is present, posing a risk of injury or death.
Innovation Solution
A slide for a firearm with a divot and a rotatable lock mechanism that allows the striker tang sear to move into a divot without trigger activation, enabling safe disassembly by rotating a lock using an actuation element like a groove or tab.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If trigger actuation is required for disassembly, then the disassembly process can be initiated, but unintended discharge may occur if live ammunition is present
Solution Approach 1:
A safety interlock mechanism acts as an intermediary between the trigger actuation and the disassembly process. The interlock includes a blocker that prevents the trigger bar from moving forward unless properly disengaged, and a detector that senses whether the chamber is clear of ammunition. This intermediary system allows disassembly to proceed safely without requiring trigger pull, eliminating the risk of unintended discharge while maintaining ease of operation.
Solution Approach 2:
The system performs preliminary detection of the ammunition status before allowing disassembly to proceed. The detector senses whether live ammunition is present in the chamber ahead of time, and only permits disassembly when the chamber is confirmed clear. This preliminary action prevents the harmful effect of unintended discharge by ensuring safety conditions are met before the disassembly process begins.
2Reliability
If a safety interlock mechanism is added to prevent unintended discharge, then safety is improved, but device complexity increases
Solution Approach 1:
The safety interlock mechanism is merged with the existing trigger assembly components. The blocker is integrated into the trigger bar structure, and the detector is combined with the existing firing mechanism elements. By merging these safety functions with existing components rather than adding completely separate systems, the patent improves reliability while minimizing the increase in device complexity.
Solution Approach 2:
The trigger bar serves multiple functions: it acts as both the firing mechanism component and the blocker for the disassembly safety interlock. The detector is integrated into the existing chamber sensing capabilities. This multi-functionality approach allows the system to achieve improved safety without proportionally increasing complexity, as existing components perform multiple roles.

AI summary
A firearm system which allows firearm disassembly without trigger actuation. The system includes a slide having a divot or cavity disposed laterally off of the main channel. This divot allows for the pivoting of the striker sleeve such that the striker tang sear can move between a first position that is engaged with a corresponding trigger bar sear of a frame and a second position whereby the striker tang sear is disposed at least partially within the divot. This allows the striker tang sear to clear the trigger bar sear for disassembly without requiring a pull of the trigger.
