Usually the modern day word for 'mate' has been abbreviated to the simpler term of 'm8'; read as 'meight'. As you know the number 9>8 therefore we have the conclusion that m9 is better than m8.

Pronounced 'mnine'.

Commonly thought of as mistakes on messenger services, however the terms are both equivalent to M8 - obviously an abbrieviation of the word "mate".
"oh hi there m9 LOL"
"hey m9, you cool you kerazy guy?"

Like a m8 but heaps cooler and more in tune with each other on a deeper level.
“Hey m9! I’m so glad we met and share such a rich, beautiful tapestry of memories together.”

“I’m not your m8 you're my m9”

M9 is rarely ever on time”

The M9, as designated by the U.S. Military is a Beretta 92FS.

Sidearm of the U.S . Military.

The M9 pistol was tested to the extremes in a competition with other gun companies to replace the existing M1911 pistol serving the U.S. military through both World Wars, Korea, and Vietnam. In 1985, the 92FS was adopted with a capacity of 15 rounds + 1 in the chamber, doubling the capacity of the old 7 + 1 capacity Colts. Though it uses the smaller 9mm round compared to the earlier .45, it has been proven just as effective, plus the 92FS allows for greater accuracy, and far better reliability. The M9 service pistol can sustain more than 35,000 rounds fired, and the 92FS jams less often then almost any other pistol.

The 92FS is designed to operate under the most adverse weather conditions. Easy dissesembly by the turning of a lever allows for field stripping in the heat of battle, as opposed to some of the previous 1911s which sometimes required special tools to open.

The 92FS can fire without a magazine by inserting a round directly into the barrel.

Beretta 92FS 9mm semiautomatic pistol as adopted by the armed forces of the United States. Probably the sexiest gun of any type ever made.
My M4 burped on a whole shitload of sand, so I whipped out my M9 and continued engaging the bad guys with it.
