Elastomeric Grip Extender for Handgun Magazine Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Extended magazines for compact handguns often protrude past the grip, causing snagging, moisture and dirt ingress, potential jamming, and loss of ergonomics due to gaps between the magazine endplate and grip, with existing solutions adding mechanical complexity, weight, and difficulty in installation or removal.
Innovation Solution
A deformable elastomeric grip extender that matches the handgun's surface finish, featuring a hollow cup for easy installation and removal without tools, securely gripping the magazine while allowing deformation for easy removal, preventing over-insertion and ensuring smooth cartridge chambering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If an extended magazine is used to increase cartridge capacity, then the magazine can hold more cartridges, but the magazine protrudes past the grip base causing gaps that lead to snagging, moisture ingress, and loss of ergonomics
Solution Approach 1:
The grip extender serves as an intermediary component between the extended magazine and the handgun grip. It fills the gap created by the protruding magazine, preventing harmful factors like moisture and dirt from entering the grip area, while also eliminating snagging issues and maintaining ergonomic control.
2Object-affected harmful factors
If mechanical parts are added to the magazine to fill the gap, then the gap is filled, but mechanical complexity and weight increase
Solution Approach 1:
The invention extracts the gap-filling function from complex mechanical components and implements it through a simple elastomeric material. The grip extender is a single-piece elastomeric component that conforms to the magazine contour, eliminating the need for multiple mechanical parts, straps, panels, and fasteners while achieving the same protective function.
3Reliability
If a tight fit sleeve is used on the magazine, then the sleeve secures the magazine, but difficulty arises in sliding the sleeve on and off
Solution Approach 1:
The grip extender employs dynamic properties of elastomeric material that allow it to deform under compression for easy installation and removal, while maintaining a secure grip during normal use. The material's elasticity provides a balance between secure attachment and ease of operation.
4Stability of the object's composition
If the grip extender is made rigid to prevent deformation, then structural stability is maintained, but ease of removal is compromised
Solution Approach 1:
The invention utilizes the parameter of elastomeric material properties that allow controlled deformation. The material maintains sufficient structural stability to secure the magazine during operation, while its elastic properties enable easy compression and deformation for installation and removal without requiring excessive force.

AI summary
An extended cartridge magazine longer than a pistol grip length needs to have the gap between the base plate of the magazine and the butt end of the grip filled. The present invention provides a sleeve to fill this gap that can be easily slid on and off the magazine by applying simple pressure to the ends of the sleeve.
