I've owned a couple M-Ns, one a rifle the other a carbine. They are well built and reliable, and ugly and accurate. The carbine was decidedly unpleasant to shoot. I could shoot 5" at 100 yards, which isn't stellar, but was about as accurate as I can shoot with open irons.

The safety is reliable, and remindes me of a safety on a .22.
