I am trying to figure out how dangerous 3d printed lower for a glock 17/19 is.

Looking for worst story's, or others experiences

Is the worst thst the lower cracks, and maybe scratches you from the force of the gun kick, or is there a chance that some part of the actual explosion can launch plastic like a grenade.
