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