Firearm Slide Guide Segmentation for Narrow Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide guide devices for semiautomatic or automatic firearms with widely configured double-stack magazines result in a correspondingly wide slide design, which is undesirable.
Innovation Solution
The slide guide device is divided into two segments: a first segment located behind the magazine chamber and a second segment located in front of it, with guide mechanisms on the frame interacting with a cartridge sliding body to allow a narrow slide design, utilizing guide projections and grooves for linear movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide rails are provided laterally on the frame to guide the slide, then reliable guiding of sliding movement is achieved, but the slide becomes wide when used with a double-stack magazine
Solution Approach 1:
The guide device is divided into two functional segments: a first guide segment laterally on the frame providing stable guidance, and a second guide segment centrally on the slide allowing compact configuration. This segmentation enables the slide to be narrow while maintaining reliable guiding through the combined action of both segments.
Solution Approach 2:
The guiding function is transitioned from a purely lateral arrangement to a combined lateral and central arrangement. The first guide segment operates laterally on the frame while the second guide segment operates centrally on the slide, utilizing different spatial dimensions to achieve both narrow slide width and reliable guidance.
2Stability of the object's composition
If lateral guide rails are used on the frame, then stable sliding movement is achieved, but the overall firearm width increases
Solution Approach 1:
The guide device is divided into two functional segments: a first guide segment laterally on the frame providing stable guidance, and a second guide segment centrally on the slide allowing compact configuration. This segmentation enables the slide to be narrow while maintaining reliable guiding through the combined action of both segments.
Solution Approach 2:
The guiding function merges lateral guidance from the frame with central guidance from the slide into a unified guiding system. The interaction between the first guide segment on the frame and the second guide segment on the slide creates a combined guiding mechanism that provides stability without increasing overall width.

AI summary
In a guide device (100) for guiding a slide (300) of a semiautomatic or automatic firearm along an upper part of a frame (200) during a sliding movement in connection with the firing of a cartridge (400), a narrow design of a slide (300) is made possible when a double-stack magazine (210) is used, in that a slideway which allows sliding between the frame (200) and slide (300) is divided into two segments (220, 240), a first segment (220) being arranged remote from barrel (230) of the firearm behind a magazine chamber (211) designed to receive a magazine (210) containing cartridges (400), and a second segment (240) being arranged close to the barrel (230) in front of the magazine chamber (211).
