Update,
I just got two mags from CDNN for my 6906 and they were shipped right in org. S&W plastic bags with S&W cardboard insert. They are fast shippers and the mags are in great shape even the plastic pinkie butt plate.. They are marked LE Law enforcement only and on one side there is numbers & holes from 5,7,9,11 and on the other side Numbers and holes from 4,6,8,10,12. My org. mags had only one side marked from 2 to 12.. I see no issues in any way with them. They look almost like new. I think they were a very good deal! George
