I am inexperienced with revolvers so maybe you can forgive my ignorance. I would like to know why it is bad to flick a revolver cylinder closed. I must admit I am guilty of doing this to the SW 617 before I'd heard it was ad for the revolver. SO I certainly hope someone can satisfy curiosity as to why it's bad. Please use terminology I can understand, I may not be up to speed on all revolver parts.
