2011 STI/Staccato Fullsize Mainspring Kit

Welcome to Extreme Shooters! We are pleased to offer you the perfect solution for your full-sized government 2011 firearms with our high-quality mainspring kit.

This mainspring kit serves as a reliable replacement kit for your government 2011 firearms, ensuring optimal performance and functionality. Additionally, it can be utilized as one of the essential components required for the full-size conversion process from a shortened Staccato C2/VIP grip to a full-sized Staccato P/XL/XC or STI grip.

Within this comprehensive kit, you will find a cap retainer pin, mainspring cap, 19lb wolff mainspring, and mainspring housing pin retainer. All these components have been blued to preserve the metal finish, adding both durability and aesthetic appeal.

    Just what I needed

    Posted by Corey on 27th Oct 2023

    Upgraded my C2 grip to a new full size grip and needed a full length mainspring. Extreme shooters offered this kit for less than others, but also ships it at a very fair and reasonable cost. It works perfectly. Thank you!
