I am sourcing mine through a local airsoft supplier. It was indicated to me that there were no guarantees it would work with a Glock 17 9mm. Nor would it be able to handle the shock and vibration from one. The frame is spec'ed to handle the shock and vibration from 22LR. I guess I will find out and see. It will apparently fit an airsoft Glock but there seems to be no interest in them so they are not moving out of inventory.
