Shadow Systems Backstrap Plug Features The Shadow Systems Backstrap Plug fills the backstrap mounting slot on compatible Shadow Systems pistols allowing the frame to be run cleanly without an interchangeable backstrap module installed. This small component gives shooters more flexibility in how they configure their pistol s grip particularly those who prefer the base frame profile without any added bulk. Shadow Systems manufactures this plug to integrate seamlessly with the rest of the pistol s frame maintaining a clean appearance once installed. Small parts like this plug are often needed when swapping between different backstrap sizes or when a shooter decides to remove a backstrap altogether. Having a dedicated plug on hand prevents a gap or loose fit in the grip frame when a backstrap module is not in use. Shadow Systems designs its pistols with modularity in mind and small components like this plug support that same philosophy by giving owners more configuration options. This part is an inexpensive way to complete a custom grip setup without needing to replace the entire frame or grip module. Shadow Systems pistol owners customizing their grip configuration can find the Backstrap Plug for sale at GrabAGun.
