Killer Innovations Gen 1 Thread Protector for Glock

Protect the performance and integrity of your threaded Glock barrel with the Killer Innovations Gen 1 Thread Protector—a rugged and precisely machined upgrade that adds both function and style to your firearm. Designed to keep your threads safe during transport, storage, or use without a muzzle device, this protector is a must-have for any Glock owner running a threaded barrel setup.

Each Gen 1 Thread Protector is crafted from premium 303 stainless steel, offering excellent corrosion resistance and long-lasting durability. Built to withstand the demands of regular use, this accessory keeps your barrel’s threads secure while maintaining a refined look that complements your overall build. Whether you’re transitioning between a compensator, suppressor, or simply shooting with the barrel bare, this protector ensures that your threads remain clean and undamaged.

Featuring a distinctive knurled texture, the Gen 1 model allows for effortless, tool-free installation and removal. The aggressive machining provides a reliable grip surface, so whether you’re working at your bench or out in the field, adjustments can be made quickly and easily—no tools required.

Unlike standard protectors, this version is designed to extend just beyond the muzzle, helping to shield not only the threads but also the 11° target crown—a critical detail for accuracy. By covering the crown, the thread protector offers an extra layer of defense against nicks, impact, and environmental wear that could otherwise compromise shot consistency.

Note: The Gen 1 Thread Protector is specifically designed for Killer Innovations threaded barrels. Fitment on barrels from other manufacturers may vary due to different threading specs or crown placement.

Due to variations in finishing and raw materials, Killer Innovations cannot guarantee exact color matches across components. However, every part is engineered for top-tier performance and visual consistency.
