Silencer Mounting Rail With Trigger Guard Support for Coaxial Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing silencers on handguns vibrate independently of the barrel, causing misalignment and preventing subsequent shots due to non-coaxial firing channels, especially in semi-automatic or fully automatic firearms.
Innovation Solution
A fastening device with a support surface and axial projection that engages with the trigger guard, ensuring contact and stability by absorbing forces and preventing tipping, even with material expansion differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the silencer is fastened to the handgun grip using a fastening rail pushed onto a mounting rail, then the silencer can be attached independently of the barrel/slide, but the silencer vibrates independently during firing causing misalignment and preventing subsequent shots
Solution Approach 1:
The patent extends the fastening mechanism from a single-plane rail connection to a three-dimensional engagement by adding an axial projection that contacts the trigger guard. This vertical dimension (axial direction) complements the horizontal rail engagement, creating multi-dimensional stabilization that prevents vibration-induced misalignment while preserving independent attachment capability
Solution Approach 2:
The axial projection with its contact surface acts as an intermediary element between the fastening rail and the trigger guard. This intermediate contact point absorbs and distributes firing forces, preventing direct transmission of vibrations that would cause the silencer to shift from its aligned position
2Reliability
If the support surface lies on the end face of the trigger guard, then contact is maintained during firing, but material expansion differences may cause loss of contact and tipping
Solution Approach 1:
The patent changes the geometric parameters of the contact interface by introducing an axial projection with a specifically designed contact surface. This projection extends into the axial direction below the support surface, creating an additional contact zone that compensates for dimensional changes due to material expansion differences during firing
Solution Approach 2:
By adding the axial projection that extends in the axial direction, the patent creates a multi-level contact system. The contact surface on the projection provides an additional contact plane that remains effective even when thermal expansion or contraction occurs, maintaining reliable contact across different materials
3Device complexity
If no axial projection is provided, then the structure remains simple, but the silencer tips downwards during firing due to gas pressure causing non-coaxial alignment
Solution Approach 1:
The axial projection is pre-positioned to contact the trigger guard before firing occurs. This preliminary contact establishes a stable reference position that prevents the silencer from tipping downwards during the high-pressure gas impulse, maintaining coaxial alignment between the barrel and silencer firing channels

AI summary
A fastening device is provided for fastening a silencer to a firearm, in particular a handgun. The fastening device has a fastening rail, wherein a support surface is formed at the rear end of the fastening rail and wherein a projection is arranged below the support surface, wherein the projection has a contact surface which corresponds at least in sections with an underside of the trigger guard and/or with a transition section between the end face of the trigger guard and the underside of the trigger guard.
