ZRTS is the only company to offer a GSG 1911-22 1 piece guide rod on the market! Don’t be fooled by the other 2-piece guide rods that can come part. Our 1 piece full length rods are more durable than the factory & 2-piece ones that show wear or even break after only 500 rounds! As seen in the picture comparing the factory and ZRTS guide rods, the ZRTS guide rod is a full length, which can help your pistol run smoother. It will also stay snug longer because the slide is guided straight back and forward on the guide rod, rather than depending so much on the frame rails for guidance. Our rods are made from stainless steel. Make sure to also consider our 1911-22 guide rod buffers!
