Magwell Adapter Sear Spring Attachment for Compact Firearm Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional magwell adapters for firearms are limited in reducing the overall size of the firearm for concealed carry due to the presence of additional components like sear springs and main spring housings, which restrict the ability to shorten the grip section without rendering the firearm inoperable.
Innovation Solution
A magwell adapter with a sear spring attachment mechanism that allows for easier magazine insertion and optional removal, featuring a sear spring aperture and attachment member that aligns with the firearm's sear spring alignment plate, enabling the adapter to be coupled and decoupled without compromising the firearm's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the grip section length is reduced to improve concealability, then the firearm becomes more concealable, but the sear spring cannot be attached and the firearm becomes inoperable
Solution Approach 1:
The invention divides the sear spring attachment function into two separate locations: the original attachment slot in the grip section and a new attachment aperture in the magwell adapter. This segmentation allows the sear spring to be supported at multiple positions, enabling the grip section to be shortened while maintaining attachment capability through the magwell adapter.
Solution Approach 2:
The magwell adapter serves as an intermediary component that provides an additional attachment path for the sear spring. When the grip section is too short to accommodate the sear spring attachment slot, the adapter mediates by providing its own attachment aperture, ensuring the sear spring can still be properly mounted and the firearm remains operable.
2Ease of operation
If conventional magwell adapters are used to facilitate magazine insertion, then magazine insertion is easier, but the adapter cannot be removed and additional components prevent grip section reduction
Solution Approach 1:
The magwell adapter is designed with dual functionality: it provides the enlarged opening for easier magazine insertion and simultaneously serves as an attachment point for the sear spring through the aperture. This multi-functionality reduces the need for separate components and allows the adapter to remain attached without adding unnecessary complexity.

AI summary
A magwell adapter is provided for use with a firearm. The firearm can include a firearm frame having a barrel section and a grip section. The grip section of the firearm can include a sear spring alignment plate, a magazine well, a sear spring, and a main spring cavity. The magwell adapter can be slidably coupled to the bottom end of the grip section of the firearm or coupled in another manner. The magwell adapter can include an aperture for receiving a tab of and holding the sear spring in place within the grip section. The magwell adapter can also include one or more pin receiving apertures adjacent to a rear end of the adapter. The pin receiving apertures can be configured to receive a mainspring housing pin to couple the mainspring housing to the magwell adapter when the mainspring housing is inserted into the grip section of the firearm.
