What is the m1911
The m1911 colt pistol was a common gun in the battlefields of CCNet. The fact its a sidearm that was quick to fire but also did damage thats slightly on par with a sword, made it be common.

The nerfed gun's state
The current nerf sent the m1911 back to worse utility than its pre gun update counterpart. For newer people and imports, pre gun update guns were absolutely horrid dealing almost not damage at all without adding in multipliers and large numbers of shooters and even then the only reason they were used was the Knockback that was present. So in short words, this means that the m1911 pistol is practically fully obsolete for military usage and even PVE. The damage is so bad that it takes a full mag to kill an unarmoured zombie and the fire rate reduced.

Causes of the nerf (assumption)
The m1911 was widely used by many militaries in CCNet. This meant that like many other stuff in CCNet it was prone to atleast one state of controversy(?) relating to a glitch. From what I was told the day m1911 got many kills, which was not too long ago, is that there was a bug that increased its damage rate while on horseback. Now how true is that, I'm not too sure, but considering the people that used it and the fact m1911 never got that many kills for the whole post gun update era, I'm gonna assume that it is indeed true.

Why the m1911 shouldnt be nerfed
The m1911 was far from an OP gun. The m1911 was simply the most melee able-to-use gun. The fact the m1911 didnt get many kills screams that it wasnt OP enough to be considered on par with swords, considering the fact m1911 pistol and sidearms in general, are short range small arms. As someone that participated to many sieges pre and post gun update, I feel like the m1911 were a very great sidearm to atleast use on melee when ure chasing people or when you dont want direct contact with your enemy. The pistol felt like a good sidearm to help repel imported armies from pvp servers, even though they werent on par with swords in terms of melee damage and only became on par if you miracously landed all shots and Im saying miracously because you aint landing all shots when someone is jumping around you and your face. In an era where we need stronger sidearms, nerfing the decent ones back to irrelevancy never seen before ever since the pre gun update era is a bad move in general, encouraging even fewer local people to participate in battles and more favours for said imports that live and die by the sword. Nerfing this gun is another step forward to club penguin weekend minigames.

This is my opinion and its bound to be biased regarding guns efficiency vs swords. I simply think nerfing this gun which was perhaps the most viable in melee, is a big L for gun users in general and a W for imported sword users that wanna make server like where they come from.
