The shot trays for the 922 are getting hard to find. I have heard that shot trays from other models also work for the 922 but I have not verified that. Another option is to get 3D printed shot trays. The 3D models can be found using this link. 3D printed trays can have issues with the pellet fit. If the pellets are too tight in the tray then light sanding for proper fit can be done. If the pellets are too loose in the tray, Plasti-Dip paint can be applied to tighten the fit up.
