I bought for few dollars a copy of the Soldier of Fortune magazine.
In the Volume 13, n. 2, February 1988 issue there is a special 8 pages article on the M9.
I put on pdf the entire article, but the file is quite big (approx. 10 MB) and I'm not able to attach it.
So here is a link where you can download the file, should someone be interested
