Polymer Composite Handgun Grip with High-Density Particles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Polymer handgun grips lack sufficient mass, leading to increased recoil and reduced aiming stability, as they are prone to limp-wristing and muzzle flip, which hinders accurate shooting, especially during rapid sequences.
Innovation Solution
A polymer composite grip module infused with high-density materials, such as metal particles, is introduced to increase the mass and density of the grip, providing a more substantial feel and improved balance by shifting the center of mass closer to the user, thereby reducing recoil and muzzle flip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If polymer material is used for handgun grip, then the grip is lightweight and resistant to environmental factors, but the grip lacks sufficient mass leading to increased recoil and reduced aiming stability
Solution Approach 1:
The patent applies composite materials by infusing metal particles (such as tungsten, steel, or other high-density metals) into the polymer matrix of the grip. This creates a composite material that combines the lightweight and environmental resistance properties of polymer with the high density and mass of metal particles, thereby reducing recoil and improving aiming stability while maintaining the base benefits of polymer construction
2Ease of manufacture
If polymer material is used for handgun grip, then the grip is mass producible, but the grip lacks sufficient mass leading to increased felt recoil
Solution Approach 1:
The composite material approach allows mass production through modified injection molding processes where metal particles are mixed into the polymer material before molding. This maintains the ease of mass production inherent to polymer manufacturing while incorporating high-density metal particles that reduce felt recoil through increased grip mass
Solution Approach 2:
The patent changes the physical parameters of the grip material by incorporating metal particles with significantly higher density than polymer (e.g., tungsten at 19.3 g/cm³ versus polymer at approximately 1.0 g/cm³). This parameter change in material density increases the overall grip mass without substantially increasing grip volume, thereby reducing felt recoil while maintaining manufacturability

AI summary
A composite grip or grip module for a handgun is made from a polymer composite that includes a polymer and dense particles that increase the density of the grip. For example, the particles can be tungsten, tantalum, lead, iron, or mixtures thereof to provide a polymer density of greater than 2.5 grams per cubic centimeter.
