Firearm Holster Slide Locking Mechanism for Accidental Discharge Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current holster designs fail to prevent accidental discharge, do not allow one-handed drawing and firing, and lack clarity on whether a round is chambered, while also compromising the accuracy and protection of sight accessories like red dot sights.
Innovation Solution
A holster with a shroud and locking mechanism that prevents the slide from moving forward, includes a locking lug to prevent chambering, and accommodates sight accessories, allowing ambidextrous use and adjustable mounting for user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a pistol is carried with a cartridge loaded in the firing chamber with the trigger actionable, then the draw and firing speed is improved, but the risk of accidental discharge increases
Solution Approach 1:
The holster applies preliminary anti-action by using a locking mechanism that prevents the trigger from being actionable during the drawing process. The lock engages with the trigger guard to block trigger movement, and the slide block prevents the slide from moving forward, thereby preventing accidental discharge before the user can safely assume control of the firearm.
Solution Approach 2:
The holster performs preliminary action by automatically chambering a round from the magazine into the firing chamber as the slide is released during the drawing process. This ensures the pistol is ready to fire immediately after being drawn, eliminating the need for manual chambering and maintaining high operational speed.
2Object-affected harmful factors
If a pistol is carried with no cartridge loaded in the firing chamber, then the risk of accidental discharge is reduced, but the time required to draw and ready the pistol increases
Solution Approach 1:
The holster performs preliminary action by automatically chambering a round from the magazine into the firing chamber as the slide is released during the drawing process. This ensures the pistol is ready to fire immediately after being drawn, eliminating the need for manual chambering and maintaining high operational speed.
3Measurement precision
If conventional sights are used on a pistol, then the pistol can be aimed, but the sights may become misaligned or contaminated when the pistol is holstered
Solution Approach 1:
The holster uses a nested doll approach by incorporating a dedicated sight accessory compartment within the holster body. The sight accessories are nested inside this protected compartment, which is accessible when the pistol is holstered but protects the sights from misalignment and contamination. The compartment can be opened to allow access to the sights for cleaning or adjustment while the pistol remains in the holster.
4Reliability
If a locking mechanism is added to prevent accidental discharge, then safety is improved, but the complexity of the holster increases
Solution Approach 1:
The holster merges multiple functions into a unified structure: the locking mechanism is integrated with the trigger guard, the slide block is combined with the holster body, and the sight accessory compartment is nested within the existing holster structure. This merging approach provides comprehensive safety and protection features while minimizing the increase in overall complexity.

AI summary
A holster includes a hip plate and a shroud mounted to the hip plate. The shroud includes a channel adapted to receive a slide of a firearm, a slide block extending into an open portion of the channel and configured to abut a muzzle end of the slide received in the channel to prevent forward movement of the slide, and a locking lug extending into the open portion of the channel and configured to engage a chamber of the slide to prevent movement of the slide.
