They are snug. Not overly loose, or tight I don't know. I have had some misfires but I can adjust the spring for that.NRA_guy said:I have never heard of that happening (but I don't own a S&W 617).
Are the unfired rounds loosy-goosy in the cylinder?
They should be ever so slightly snug.
I read somewhere that the holes in the cylinder on a S&W 617 are especially tight and must be cleaned regularly in order to get the empties out easily. Makes me wonder if maybe somebody "worked" on yours.
