Semi-Automatic Pistol Slide Pull Apparatus for Stable Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users, especially occasional shooters like teenagers and women, face difficulty in pulling the spring-loaded slide of a Glock semi-automatic pistol, leading to time wastage and inaccuracy due to the need to use thumb and index fingers, causing the hand holding the pistol to move.
Innovation Solution
A slide pull apparatus with a shell that partially encloses the rear portion of the slide, featuring sidewalls with ribs and laterally projecting finger tabs to facilitate a rearward pull, allowing for easier and more stable operation of the slide.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the slide is pulled using thumb and index fingers, then the slide can be engaged, but the hand grasping the pistol moves causing time wastage and inaccuracy
Solution Approach 1:
The slide pull apparatus serves as an intermediary tool between the user's fingers and the pistol slide. The apparatus includes a shell with finger tabs that fit over the user's fingers, providing a stable platform to engage and pull the slide without causing the hand to move, thus eliminating time wastage and inaccuracy.
Solution Approach 2:
The slide pull apparatus is segmented into distinct functional components: a shell portion that encloses the rear of the slide, finger tabs for user engagement, and sidewalls with ribs for structural support. This segmentation allows each component to perform its specific function optimally while working together to solve the overall problem of stable slide engagement.
2Ease of operation
If the slide is pulled using thumb and index fingers, then the slide can be engaged, but the hand grasping the pistol moves causing inaccuracy in hitting the target
Solution Approach 1:
The slide pull apparatus acts as a mediator that isolates the sliding motion from the hand's position. By providing a stable, fixed reference point through the shell and finger tabs, the apparatus allows precise slide engagement without transferring movement to the hand, thereby maintaining target accuracy.
Solution Approach 2:
The apparatus applies local quality by providing different functional characteristics at different locations: the shell provides enclosed protection and structural integrity at the rear of the slide, the finger tabs provide precise engagement points, and the sidewalls with ribs provide lateral support. This localized optimization ensures accurate slide engagement without affecting hand stability.
3Ease of operation
If a slide pull apparatus is introduced, then slide engagement becomes easier and more stable, but the device complexity increases
Solution Approach 1:
The apparatus is divided into simple, distinct segments: a shell portion, finger tabs, and sidewalls with ribs. Each segment is a simple geometric form that performs a specific function. This segmentation allows the complex function of stable slide engagement to be achieved through the combination of simple, easily manufactured parts.
Solution Approach 2:
The slide pull apparatus is designed to be universal for Glock semi-automatic pistols, fitting the specific geometry of the slide and trigger assembly. The shell, finger tabs, and sidewalls work together as a multi-functional unit that provides engagement, stability, and structural support, justifying the added complexity through versatile functionality.

AI summary
Disclosed is a slide pull apparatus for aiding in pulling a slide on a semi-automatic pistol. The slide pull apparatus includes a shell configured to partially enclose a rear portion of a slide on a semi-automatic pistol, the shell including: a plate having an aperture of a size configured to surround at least a portion of a rear aim sight on the semi-automatic pistol. The slide pull apparatus additionally includes at least one finger tab projecting from the slide pull, the finger projection having a size configured to accommodate at least one finger of a human hand, wherein pulling on the at least one finger tab in a rearward direction causes the slide to move in a rearward direction, thereby facilitating loading of the semi-automatic pistol.
