Our Gen. 4 guide rods have really taken off! I have been absent on this forum for a while, so the first person who replies wanting a Glock Gen. 4 guide rod for G17, G19, G34 or G35 will receive one for FREE! Our guide rods have been credited with helping many suffering from the Gen. 4 malfunctions that have been experienced by some. Our guide rods are complete Gen. 4, not simply an "adapter" which uses a Gen. 3 rod. The Gen 3 rods do not sit in the frame properly, and the back of the smaller Gen. 3 guide rods swim in the larger Gen. 4 frame channels. The MAJOR beneft of using a steel guide rod is to promote consistent cycling, just as was the purpose in 1911's. Using a Gen. 3 rod in a Gen 4 frame will NOT propmote consistent cycling. Thanks again fellow GT'ers, and first to respond is the winner. jager Wanna kill these ads? We can help!
