This is the factory Glock 9mm barrel that comes stock in the Glock model 17C. It cannot be used as a compensated barrel in the 17 due to the lack of ports in the side. Using it to convert the 22C or 31C to shoot 9mm is not recommended and unsafe as it is not a 100% fit. This barrel will not work extended in the 19C or 26 due to the difference in the locking blocks.
