honestly what is wrong with this plugin why is it so spaced out why do half of the weapons not even work is this plug-in dead?

Have you tried playing with the config at all? there seems to be an option to adjust the spacing

"2.6 Spacing": {
      "2.6.1 horizontal": 0.0,
      "2.6.2 vertical": -0.005
    },

As for the missing weapons, the current maintainer of the plugin would probably have to add support for them.
