>Worst case it launches the slide into your face
With the way it is designed (all Glocks really), any catastrophic failure rearward with the slide nailing you in the dome first requires the recoil spring to be fully compressed, then somehow still having enough energy to rip the front rails out, rip the locking block out, then rip the rear steel rails/grip reinforcement out of the frame, through the web of your hand.
In short, with a 22lr, it ain't happening chief.
Launching it forward though is a definite possibility. They're designed to be taken apart that way in the first place, and it's only one little funny plate at an angle that keeps it in check.
