1911 Frame Relief and Ambidextrous Slide Stop for Debris Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 1911 handguns face challenges in customization due to unitary grips and frames, which complicate the addition of features like gas pedals and optics, and may reduce resale value or cause functional issues.
Innovation Solution
A modular firearm frame with a recessed socket face and removable finger interface allows for easy attachment and removal of accessories without altering the frame, along with a trigger shoe assembly featuring a dovetail design for secure and adjustable engagement, and a magazine catch retainer plate for enhanced compatibility with various magazines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a unitary grip and frame are used in conventional 1911 handguns, then the structural integrity and simplicity are maintained, but customization of features like gas pedals and optics becomes difficult and may reduce resale value or cause functional problems
Solution Approach 1:
The frame is segmented into a unitary frame portion and a separate customizable grip portion. The grip portion can be removed and replaced with different configurations (e.g., extended grips, grips with integrated optics mounts, or grips with gas pedal attachments) without modifying the main frame structure. This allows customization while preserving the integrity of the original frame.
Solution Approach 2:
The grip portion serves multiple functions: it provides the basic gripping surface, can be configured with extended surfaces for better hand placement, can incorporate optics mounting surfaces, and can include attachment points for gas pedals. This single replaceable component addresses multiple customization needs that would otherwise require separate modifications to the frame.
2Adaptability or versatility
If accessories are mounted on conventional 1911 frames by replacing the slidestop or making aftermarket holes, then customization is achieved, but locking the slide becomes difficult or the pistol's resale value and functionality are reduced
Solution Approach 1:
The grip portion is designed as a separate replaceable component that can incorporate accessory mounting features (optics rails, gas pedal attachments) without requiring modifications to the frame's slide locking mechanism. This segmentation ensures that the critical slide stop function remains intact while allowing extensive customization of the grip area.
3Adaptability or versatility
If conventional 1911 configurations are used, then the traditional design and reliability are maintained, but mounting of traditional optics and other accessories is prevented or not securely attached
Solution Approach 1:
The customizable grip portion can be configured with various mounting surfaces and attachment mechanisms designed specifically for different types of accessories including traditional optics, red dot sights, and gas pedals. The grip acts as a universal mounting platform that secures accessories directly to the firearm structure rather than requiring separate mounting systems.

AI summary
The application pertains to 1911 style firearms. The firearms can have a relief and/or an ambidextrous slide stop. The firearm frame can have a relief to capture debris. The relief can sit below where the barrel sits once assembled with the frame. The relief can be shaped such that debris that would typically be held in the barrel void would instead fall into the relief. The firearm can have an ambidextrous slide stop. The slide stop can incorporate a male-female interlocking mechanism allowing for secure and removable coupling.
