Modular Autoloading Pistol Handgrip for Angled Magazine Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autoloading pistol designs require simultaneous removal of the handgrip and trigger guard for interchangeable magazine attachment, limiting versatility and cartridge capacity, and do not accommodate different magazine angles and calibers effectively.
Innovation Solution
A removably attachable handgrip module with flange extensions and slideable insertion into the frame/trigger housing assembly, allowing non-parallel magazine bore alignment and attachment without removing the trigger guard, facilitating interchangeable handgrips for various magazine angles and calibers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the handgrip and trigger guard are simultaneously removed for magazine interchangeability, then magazine compatibility is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The handgrip assembly is segmented from the trigger guard assembly, allowing the handgrip to be removed and replaced independently while the trigger guard remains attached to the frame. This segmentation enables magazine interchangeability without requiring removal of the entire handgrip and trigger guard assembly, thus improving ease of operation while maintaining magazine compatibility.
Solution Approach 2:
The trigger guard is designed with universal attachment features that can accommodate multiple handgrip configurations and magazine types. The trigger guard serves as a universal mounting platform that remains fixed while different handgrips with various magazine capacities and angles can be attached, providing multi-functionality and versatility.
2Reliability
If the handgrip is fixed to the frame for structural stability, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The attachment mechanism transitions from a fixed, permanent connection to a dynamic, reversible connection. The handgrip can be securely attached when needed for stability during firing, and easily removed or exchanged when magazine interchangeability is required. The attachment features provide reliable mechanical engagement during operation while allowing quick changes when needed.
3Ease of manufacture
If the magazine bore is aligned parallel to the handgrip centerline for manufacturing simplicity, then ease of manufacture is improved, but adaptability deteriorates
Solution Approach 1:
The magazine bore is intentionally positioned at an asymmetric angle relative to the handgrip centerline, creating a non-parallel alignment. This asymmetric positioning allows the magazine to be inserted at optimized angles for different caliber cartridges and magazine designs, improving adaptability while the manufacturing process accounts for this predetermined angular offset.
Solution Approach 2:
The magazine bore alignment is optimized locally within the handgrip structure rather than being constrained by a global parallel alignment to the handgrip centerline. This local optimization allows the magazine chamber to be positioned at the ideal angle for reliable feeding and extraction, while the overall handgrip geometry maintains ergonomic qualities.

AI summary
A modular autoloading pistol is presented, capable of accommodating a releasably attachable handgrip module. The handgrip module is slidably attachable to a lower receiver, which is inclusive of a trigger housing appendage having a trigger guard, and having an interconnection feature for receiving the handgrip module. The releasably attachable handgrip is designed to receive a double stack magazine at a predetermined angle of insertion. The predetermined angle of insertion may be different from the angle of the handgrip centerline. Advantageously, interchangeable handgrips may accommodate different magazines at different predetermined angles of insertion.
