The M7 is a real fighting knife

[m9er]

Never used one in the "fighting knife" role, just like collecting them and have a "beater" that I use from time to time. To me the M7 definitely looks and feels better than the M9 when mounted on the A1. To me, just the little extra weight of the M9 makes a big difference in the balance of the rifle when compared to the M7.
