    The recoil spring guide rod also acts as a standoff device, as the end of the rod protrudes from under the barrel and keeps the slide in battery when pressed against an object such as someones's chest in contact-distance self-defense situations. This prevents the slide from being moved back because the device pushes the surface area of objects ...
